Describe the bug
Can't we use both normal username password sign in and social sign in?

To Reproduce
Steps to reproduce the behavior:

Have both username/ password signin and social signin in the same app

Expected behavior
D/AWSMobileClient(20596): Using the SignInProviderConfig from `awsconfiguration.json`. W/AWSMobileClient(20596): Failed to parse HostedUI settings from store.

Hi @niyonx thanks for opening this issue.

Username and social login should be able to configured at the same time. Looking at the error logs you pasted, it contains awsconfiguration.json which seems odd, as in amplify-flutter this file is not in the scope.

Could you provide some details to help us understand this issue?

What version of amplify-flutter libraries you are using? (can paste the content of pubspec.lock file)

Have both username/ password signin and social signin in the same app
How did you configure?

Also could you paste the content of the generated amplifyconfiguration.dart?

niyonx · 2021-12-13T23:36:51Z

Yes I'm not sure why it is using the awsconfiguration.json instead of the amplifyconfiguration.dart. Here is the contents of pubspec.lock.

Thanks @niyonx .

In what environment you are testing the App? Android emulator, physical Android device? Do you have Chrome installed?
Could you also provide the AndroidManifest.xml file of your App?

niyonx · 2021-12-14T15:43:35Z

I am testing on an android emulator. Yes I have chrome installed.

I actually forgot to modify the AndroidManifest.xml. Now the actual sign in sign up are working, but I still get some errors on the amplify configuration. It is still using config from awsconfiguration.json for some reason.

HuiSF · 2021-12-14T16:38:14Z

Thanks for the follow up @niyonx and I'm glad the social sign in is working.
Will look into the exception thrown about awsconfiguration.json.

HuiSF · 2021-12-14T17:01:56Z

The exception seems caused by this issue aws-amplify/amplify-android#1180 when configuring and using both user name login and social login.

ben-the-developer · 2022-08-17T15:37:27Z

Hi everyone, I am experiencing a similar issue by introducing the basic sign in with username/password and social sign in with Google and Facebook to the same app. I am using amplify_flutter 1.0.0-next.0+1, and test it in Android emulator Pixel 4 with API 33.

The error I get is

I/flutter (16849): ERROR | SignInStateMachine | Emitted error: UserNotFoundException {
I/flutter (16849):   message=User does not exist.,
I/flutter (16849): }

When I remove the OAuth section in the awsconfiguration.json, then the username/password sign in can work. But when I add the OAuth section back, then the username/password sign in starts throwing exception.

May I ask if there is any update? Or is there any workaround? Thank you

dnys1 · 2022-08-17T17:23:40Z

Hi @ben-the-developer, this use case should be supported in our dev-preview. Would you be willing to create a separate ticket with the methods you're calling and your full configuration file? You mention awsconfiguration.json but this is typically not used for Flutter apps - do you mean amplifyconfiguration.dart? Cheers!

ben-the-developer · 2022-08-18T12:24:33Z

Hi @dnys1 , yea, it's amplifyconfiguration.dart. I will start a new ticket to describe my question.

Jordan-Nelson · 2022-08-23T17:01:27Z

@niyonx - Were you able to get sign in fully working? If so, I think the logs you are seeing can be safely ignored.

I also wanted to not that we have recently released a new developer preview version of the Auth category (amplify_flutter v1.0.0-next.0). This new version is a full re-write of the auth category in dart. I don't think you will see this issue in this version as it doesn't depend on Amplify-Android.

You can read more about the developer preview release in the blog post and docs.

Let me know if the issue you saw was preventing sign in from functioning or if you were just observing the messages in the logs.

Jordan-Nelson · 2022-09-19T20:25:25Z

@niyonx - Please let me know if you are still facing an issue. Otherwise I will close this issue out.
