Issue: Upon trying to swap with the public Uniswap app to Holdenomics token (address 0x1d7e00a59297161d1733897b5add6a382cc6bf2a) the routing API returns no route found.

Expected behaviour: The API returns a route, as with other tokens.
Actual behaviour: No route found.

When the auto router API is turned off in settings, the V2 LP is found and trades can occur.

When I follow the document, I can easily install it in aws. But for some reason I need to run this api locally or on a VPS. How can I do that?

I want to start a local service to test the current project, so I tried many methods. There is nothing better than localstack. I studied it, but it is stagnant at present, so I hope to have relevant local test documents. Thank you

I deployed but am getting this error :

swap:1 Access to fetch at 'https://9jgm12ala1.execute-api.us-east-1.amazonaws.com/prod/quote' from origin 'http://localhost:3000' has been blocked by CORS policy: Request header field x-request-source is not allowed by Access-Control-Allow-Headers in preflight response.

After deployed the stack, I got the url like:

Outputs:
RoutingAPIStack.Url = https://xxxxxxx.execute-api.ap-southeast-1.amazonaws.com/prod/

BTW, this is my .env:
THROTTLE_PER_FIVE_MINS = '' # Optional
WEB_RPC_1 = "https://mainnet.infura.io/v3/xxxxxxxxxxxxxxxxxxxxxx"

Then I send the query :
curl --request GET 'https://xxxxxxxxxx.execute-api.ap-southeast-1.amazonaws.com/prod/quote?tokenInAddress=0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2&tokenInChainId=1&tokenOutAddress=0x1f9840a85d5af5bf1d1762f925bdaddc4201f984&tokenOutChainId=1&amount=100&type=exactIn'

Getting internal_error:
{"errorCode":"INTERNAL_ERROR","detail":"Unexpected error","id":"fee8f"}

And the id is different each time I try to query the same params.

Is therr any configs I set wrongly?

Hi,
There is a problem that I am trying to figure out since 1 day, the APIs are successfully deployed on AWS. But during API calls It returns an internal server error in response. can any one helps me to understand the aws secret manager to write the secrete in the aws code.

"After successfully deploying the routing-api, I attempted to invoke it using the command: curl --request GET 'https://xxxxx.execute-api.xxx.amazonaws.com/prod/quote?tokenInAddress=0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2&tokenInChainId=1&tokenOutAddress=0x1f9840a85d5af5bf1d1762f925bdaddc4201f984&tokenOutChainId=1&amount=100&type=exactIn'. However, it resulted in an error:
{"errorCode":"INTERNAL_ERROR","detail":"Unexpected error","id":"0e6df"}.

Below is my .env file configuration. I am wondering if there is an error in my .env file setup. The code is based on the latest commit ab901a7.

I got an error message when deploying a RoutingAPIStack.
There is already a Construct with name 'RoutingAPI-SEV3-Simulation' in RoutingAPIStack [RoutingAPIStack]

In routing-api-stack.ts, 'simulationAlarmSev2' and 'simulationAlarmSev3' are the same alarm name 'RoutingAPI-SEV3-Simulation'.

Currently there is no way of knowing what cached pool data is available to grab through ipfs so we want to add a record that populates the urls for fetching pool data on ipfs for the various chains

Hi! thanks for this excellent piece of software. I have deployed RoutingAPIStack to AWS and am surprised by the relatively high AWS charges. I have $25 in lambda usage fees despite only having used the API for less 100 queries over 6 days.

Specifically, I see the following in my AWS bill:

AWS Lambda - Total Compute - US East (Ohio)-Tier-1 | 1,563,577.501 Lambda-GB-Second   USD 26.06

If this bill scales w/ actual usage it won't be feasible for me to integrate this API--and Uniswap--with my product. Is there a large upfront cost to setting up the RoutingAPIStack, perhaps upfront caching, or should I expect the cost to scale linearly with my users?

Hi,
There is a problem that I am trying to figure out since 1 day, the APIs are successfully deployed on AWS. But during API calls It returns an internal server error in response. I followed the steps in the documentation which is connected to an AWS account and it deployed successfully.

In the latest update for the blocklist the update includes an entry for

b493f3a#diff-3b254b61721239b3517f6d8212a09403b8231d3852cfe70e2ec73b048fee3155R1109-R1112

      "name": "ENS DAO",
      "symbol": "ENS",
      "decimals": 18

This is a fake ENS DAO token. The correct token contract is at 0xC18360217D8F7Ab5e7c516566761Ea12Ce7F9D72.

Can you add clarification that its blocked because its fake, under the keyword values

Thanks

Hey Uniswap Team,
I was trying to make the necessary changes to get the routing api server work for our chain, hence i needed a local environment, some searching showed, aws sam could be used to test it out locally, so i did cdk synth , gave the template files for different region out into sam build <path to one of the region template file>,
and used the command sam local start-lambda to run the api server
issue is am trying to run the curl command given in the readme.md of the repo :
"curl --request GET '<INSERT_YOUR_URL_HERE>/quote?tokenInAddress=0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2&tokenInChainId=1&tokenOutAddress=0x1f9840a85d5af5bf1d1762f925bdaddc4201f984&tokenOutChainId=1&amount=100&type=exactIn'
" but i seem to be getting the error, query parameters are not supported is it because aws sam cannot be used to deploy the routing api locally or the readme.md is outdated and the api has been changed into a post?

Each time the error Unexpected error. is returned, log is fired with more information. I would like to know, where I can even see this log entries. I also don't believe that returning Unexpected error. error message somehow provides more security then Unexpected error building request injected. error message for example or that it has any other benefit at all.

It wouldn't require much effort to change error messages, I could do it based on log entries, but it wouldn't alleviate this issue entirely as log entries are pretty cryptic as well.

https://github.com/Uniswap/routing-api/blob/954e04080dbc41cc899b5f157cf10093b3866914/lib/handlers/handler.ts#L75C1-L84C2

Not sure exactly why this happens, but if you quote large amounts the routing breaks.

Take this example:

100,000 Matic yields more during the swap then 1,000,000 matic

While this may not seem like a major issue in this context, it is when you have a smaller amount of liquidity, and your using mixed routing for v2/v3.

Follow the readme, but throw error when fetch quote

Environmental variable QUICKNODE_42220 isn't defined!

and

Failed to get gas constants data from the optimism gas oracle

I don't know what happened

I've deployed the API to an AWS stack but I want to deploy to my Linux server too. How can I done that? I've tried to create and run a Docker container but it didn't work.

If the idea is to keep routing-api inline with SOR usage, the .env variables should be:

   JSON_RPC_PROVIDER_{CHAIN NAME} = { RPC Provider}
   # Ex: JSON_RPC_PROVIDER_MAINNET
   ...

It's also a lot easier to read

Also update README to remove // in example CURL req
curl --request GET '<INSERT_YOUR_URL_HERE>/quote?tokenInAddress=0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2&tokenInChainId=1&tokenOutAddress=0x1f9840a85d5af5bf1d1762f925bdaddc4201f984&tokenOutChainId=1&amount=100&type=exactIn'
to
curl --request GET '<INSERT_YOUR_URL_HERE>quote?tokenInAddress=0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2&tokenInChainId=1&tokenOutAddress=0x1f9840a85d5af5bf1d1762f925bdaddc4201f984&tokenOutChainId=1&amount=100&type=exactIn'

I had this issues while while fetching pools on the subgraph

As a result poolCache.json for chains like polygon aren't created, so the routing-api can't work.

xxx is the infuraId or alchemyId

Or are there any public routing URL services for the uniswap widget?

Similar to #54
Can use script logic for cron job

THROTTLE_PER_FIVE_MINS = '' # Optional

RPC Providers must be set for the following CHAIN IDs:

BNB = 56

TENDERLY_USER = '' # For enabling Tenderly simulations
TENDERLY_PROJECT = '' # For enabling Tenderly simulations

I have set the rpc url but its throw internal server error, Can you please update a required field in sample env file for better understanding.

Thanks.

I successfully deployed and used routing api. I then undeployed it running cdk destroy RoutingAPIStack. Now when I try to deploy it again a get an error at some point during deployment process. I'm not sure how to diagnose this. I tried to revert back to the older version of routing api I used previously. I tried to delete s3 buckets that were left after the process and repeated bootstrapping process hoping to arrive at a known state. Now my only assumption would be that the problem is that I use AWS CDK v2, which documentation says should be compatible anyways.

I want a confirmation if the problem is on my end or not and to take a hint as to what is the source of the problem and how to fix it.

Hi everyone,

As I check in this code https://github.com/Uniswap/routing-api/blob/main/lib/handlers/quote-to-ratio/quote-to-ratio.ts#L518-L522, currently this routing-api does not account for the pools with tick spacing = 1.

Is it because of the performance issue? For tick spacing = 1, the algo must go through too many loops, which slow down the response time drastically?

Thanks

Hello, we are using the routing API and would like to spin up multiple routing API nodes with connections to different rpc URLS. It seems currently this project depends on an infura project ID. Is there a workaround or is roadmapped?

Cheers thanks for the project,
Kyle

Move swap route transformation to json response to @uniswap/router-sdk https://github.com/Uniswap/routing-api/blob/main/lib/handlers/quote/quote.ts#L224

Logic is copy-pasted into the interface at the moment and could be shared.

Issue

• Routing requires a list of all pools in V3. This data is not easily available on-chain, so today we pull it from the Subgraph.
• To minimize dependencies on the Subgraph and improve latency, we have a cron job that runs every 5-10 minutes. It queries the Subgraph to get all the pools, and saves them into S3. Each request to the routing API queries this file in S3 to gets the list of pools.
• For client-side routing we want to remove dependencies on hosted services, therefore we would like to move this pool cache file to IPFS. The interface would then query IPFS to get pools for routing.
• Since IPFS files are immutable, and we'd like to update this pool cache every few minutes, we need to put it behind a stable IPNS address.

Tasks

• Run plan by legal around storing this pool cache, and whether it can contain blocked tokens or not
• Update cron job to publish the pool list to IPFS/IPNS
• Update routing API to read pools from IPNS instead of S3

There should be a helper to convert the route from SwapRouter in SOR to the JSON route returned by routing api

I can't use arbitrum network in .env file,now is it support?

Disable the Auto Router IP and the transaction works as expected.

As per this issue in aws-cdk:
aws/aws-cdk#19836

they are stoping the support of v1 by 1st of June. Please can we migrate from v1 to v2?

Optimism is updating their sequencer to use a compression alg for lower gas costs. Since we are calculating the gas manually in the gas model we'll need to update the calldata bytes to reflect how the compression is generating calldata.
