lnd-grpc-client's Issues

lookup_invoice is not returning with the expected format

Not sure if this is an issue with lnd-grpc-client or lnd itself, (trying to find out),

When I call lookupinvoice with the lncli I get a response that includes fields I need:

"amt_paid": "0",
    "amt_paid_sat": "0",
    "amt_paid_msat": "0",
    "state": "CANCELED"

But when I run via lnd-grpc-client I get a different response that is missing these fields:

r_preimage: "\240\262.\331*\010\265&\257m\226\t\025\301_\2658\267\355X\343B8\213|\361!\005w\302\366\022"

add_index: 163

How can I get a response that includes amount paid?

I tried generating my own rpc_pb2.py using protoc rpc.proto but even then I get a response that differs from lndcli

...
expiry: 3600
cltv_expiry: 40
add_index: 160
value_msat: 2825000
features {
  key: 9
  value {
    name: "tlv-onion"
    is_known: true
  }
}
features {
  key: 14
  value {
    name: "payment-addr"
    is_required: true
    is_known: true
  }
}
features {
  key: 17
  value {
    name: "multi-path-payments"
    is_known: true
  }
}

This looks closer but is still missing what I need. Is this perhaps an issue with lndrpc itself?

Any help would be greatly appreciated. Otherwise I'm going to have to use ssh and subprocesses...

How to make a payment with many parameters

I am confused by the send_payment method, I am trying to use it similarly to other methods, but it says the argument does not exist.

Any idea what am I doing wrong, I am trying to do a circular rebalance?

Do you know if this is using paymentV1 or PaymentV2?

Is there an easy way to get this as a json or dict?

Does `client.subscribe_invoices()` work?

Hi, cool library, thanks!

I've been successfully using it for creating invoices, but when I iterate on client.subscribe_invoices() I don't get anything yielded at all when I create new invoices.

Have you had this working? Thanks!

Add support for new grpc methods in LND 0.4.1

Running on flask in production

I'm having trouble running this in Flask in production. Running on localhost the exact same code works fine. I'm thinking it has to do with a permission issue. How do I make sure that my Flask site can execute the code?

from lndgrpc import LNDClient # for LND rpc

def addInvoice(amount, memo):
    INVOICE_MACAROON_FILEPATH = '/home/ekerstein/.lnd/invoice.macaroon'
    lnd = LNDClient('127.0.0.1:10009', macaroon_filepath=INVOICE_MACAROON_FILEPATH)
    return lnd.add_invoice(amount, memo).payment_request

@app.route("/addinvoice")
def add_invoice():
    amount = request.args.get('amount', type = int)
    memo = request.args.get('memo', type = str)
    return jsonify(addInvoice(amount, memo))

Looking for a bit of help getting started using gRPC with Umbrel

I'm able to connect to my Umbrel using the REST API but I'm struggling with getting gRPC (which I think I need for being able to send Keysend payments).

macaroon_folder = ".macaroon"
macaroon_file = "admin.macaroon"
macaroon_path = os.path.join(macaroon_folder, macaroon_file)
cert = os.path.join(macaroon_folder, "tls.cert")

lnd = LNDClient(
    macaroon_filepath=macaroon_path,
    cert_filepath=cert,
    ip_address="10.0.0.5:10009",
    network="mainnet",
    admin=True
)

always give me this when I try lnd.get_info()

Exception has occurred: _InactiveRpcError       (note: full exception trace is shown but execution is paused at: _run_module_as_main)
<_InactiveRpcError of RPC that terminated with:
	status = StatusCode.UNAVAILABLE
	details = "failed to connect to all addresses"
	debug_error_string = "{"created":"@1631694216.210741000","description":"Failed to pick subchannel","file":"src/core/ext/filters/client_channel/client_channel.cc","file_line":3187,"referenced_errors":[{"created":"@1631694216.210741000","description":"failed to connect to all addresses","file":"src/core/lib/transport/error_utils.cc","file_line":146,"grpc_status":14}]}"
>

I'm not sure where I'm going wrong. I'm absolutely certain my umbrel is on 10.0.0.5 on my local net. Docker on the Umbrel seems to be exposing the right port:

405098eccf22   lightninglabs/lnd:v0.13.1-beta   "lnd"                    23 hours ago   Up 13 hours   0.0.0.0:8080->8080/tcp, :::8080->8080/tcp, 0.0.0.0:9735->9735/tcp, :::9735->9735/tcp, 0.0.0.0:10009->10009/tcp, :::10009->10009/tcp   lnd

Really grateful for any help anyone can offer.

can not create new wallet with lndgrpc.

hi there,
I can't create new wallet with lndgrpc. do you know what's the problem?

Add timeout constraint to macaroon when making RPC calls

https://github.com/lightningnetwork/lnd/blob/master/docs/macaroons.md mentions

lncli also adds a caveat which makes it valid for only 60 seconds by default to help prevent replay in case the macaroon is somehow intercepted in transmission.

I think we could also do this to match the security protections of lncli. This is an enhancement request to add time caveat when using the macaroon.

Suggested way to implement this:

Use pymacaroons library https://github.com/ecordell/pymacaroons
Before every RPC call

from pymacaroons import Macaroon

m = Macaroon.deserialize(original_macaroon)
m.add_first_party_caveat('X=Y')
m.serialize()

For 'X=Y' generate the constraint base on current wall time to match the behaviour of lncli's function macaroons.TimeoutConstraint
(call is here:
https://github.com/lightningnetwork/lnd/blob/158a32c4e1a472dfae446478845c0a96e67dd4f7/cmd/lncli/main.go#L117 , definition is here https://github.com/lightningnetwork/lnd/blob/c1c4b84757dd5b1e1fcb285b4a1fa6a56b35432c/macaroons/constraints.go#L46 )
TimeoutConstraint calls TimeBeforeCaveat in checkers https://sourcegraph.com/github.com/go-macaroon-bakery/macaroon-bakery/-/blob/bakery/checkers/time.go#L33:20 which basically adds "time-before=Z" where Z is UTC time in RFC3339Nano format https://sourcegraph.com/github.com/go-macaroon-bakery/macaroon-bakery/-/blob/bakery/checkers/time.go#L34 For example: "time-before=2019-01-02T15:04:05.999999999Z07:00"

Add fwdinghistory method

Hello, first, I love the library which made it much easier for me to work with the grpc lnd client.

That said, the one feature I needed to build my app uses the 'fwdinghistory' argument from lncli, would it be possible to add that as a method in your library - I tried looking for it, but doesn't seem to exist, if it does, please let me know.

Thank you for your time and contribution to the LN ecosystem.

Peer name is not in peer certificate

Hi, I'm trying to run:

Is there an additional step that needs to be done for TSL other then just copying over the "tls.cert" file?
