Why import aws-amplify-react if you are not going to use it anywhere?

This sample should be updated to also take advantage of aws-amplify-react and the withAuthenticator HOC since that is the path that the vast majority of users will tread with AWS-Amplify Auth.

A section on Social SignIn is also badly needed especially around integrating with IdPs like Twitter that are not natively supported on the Amplify / Cognito dashboard.

I managed to get this running on my local emulator. However, I am not able to read any type of console.logs. When I start the bundler the app will load just fine, but then I get this message

::ffff:127.0.0.1 - - [15/Jan/2020:08:25:15 +0000] "GET /index.delta?platform=android&dev=true&minify=false HTTP/1.1" 200 - "-" "okhttp/3.11.0"
::ffff:127.0.0.1 - - [15/Jan/2020:08:25:16 +0000] "GET /assets/src/assets/amplify.png?platform=android&hash=ea2db77f232a3a0a8fd05daf95808cdc HTTP/1.1" 200 - "-" "okhttp/3.11.0"

When I reload, I get

DELTA [android, dev] ....../index.js ░░░░░░░░░░░░░░░░ 0.0% (0/1)::ffff:127.0.0.1 - - [15/Jan/2020:08:28:05 +0000] "GET /index.delta?platform=android&dev=true&minify=false&deltaBundleId=501f65faf0ae5cbc HTTP/1.1" 200 69 "-" "okhttp/3.11.0"
DELTA [android, dev] ....../index.js ▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓ 100.0% (1/1), done.

Everything else seems to work just fine. Any ideas on why I'm not seeing any console.logs?

Issue: aws-amplify/amplify-js#3868 (comment)

I have deployed using the click to deploy button.

While trying to sign in i get this error:

error signing up:  
Object { code: "InvalidParameterException", name: "InvalidParameterException", message: "Invalid phone number format." }

I get this whether the format is +1 999-999-9999 or 999-999-999 which should work if I am reading the following correctly:

    composePhoneNumber(dial_code, phone_line_number) {
        return `${dial_code || '+1'}${phone_line_number.replace(/[-()]/g, '')}`;
    }

This is probably an FAQ or doc update, but if you hit this issue, you can work around it by copying ANY debug.store to
/...yourpath.../aws-amplify-auth-starters/android/app/debug.keystore

For example:
cp /...yourpath.../aws-amplify-auth-starters/node_modules/react-native/template/android/app/debug.keystore /...yourpath.../aws-amplify-auth-starters/android/app/

And then the build worked.

I have created a live demo of using this AWS Amplify for Auth on https://um-app.t3chflicks.org/ and the code can be found here https://github.com/sk-t3ch/AWS-user-manager-app-quickstart. I also wrote a couple of blog posts about it pt. 1 and pt. 2.

I am just trying to share resources I wish I had when starting.

I hope this project will accept showing this as an example of a live demo :)

Walking through the README and then trying to create a user, the sign-up page gives an error:

Attributes did not conform to the schema: custom:favorite_flavor: Attribute does not exist in the schema

Commenting out the relevant line makes the error go away, but it makes me wonder if the intent was to have the schema include a custom attribute?

I am trying to run "npm install -g @aws-amplify/cli" on my MAC - Mojave OS.
every time I am getting this error:
"The operation was rejected by your operating system.
It is likely you do not have the permissions to access this file as the current user".

I am not sure where to start but here is what is spit out when I try to install the node modules...

I wish to use this but already have a cognito user pool that I want to reuse. Can I attach the existing pool instead of creating one? Specifically, where can I configure the pool name/arn?

When you run npx react-native run-android and you've never run amplify init before you will get a lot of missing file errors related to AWS (I didn't capture the log sorry). Once you do run init though you can run the android build and it will launch in the virtual Android device.

I think the README just needs a tweak so you run amplify init before you run the build.
You CAN run the build before you push, you'll get a different error but you can see the app launch which is great for beginners. You should probably recommend running push first though as well.

I have new laptop and I think this is why I hit this; if you've run amplify init before I don't think you will.

Hello @jpeddicord and @dabit3, we are trying to implement this solution in one of our React applications. We downloaded the react example and tied it to our existing Cognito User Pool. Authentication works fine, but when we try to enable TOTP for a user we are always getting this error

{__type: "EnableSoftwareTokenMFAException",…}
message: "Code mismatch and fail enable Software Token MFA"
__type: "EnableSoftwareTokenMFAException"

The apps we used to generate the TOTP code were Authy and Google Authenticator

Can you verify if there are any issues with the React version of this sample? or it could be a configuration issue in Cognito?
