Create client failed with Failed to get credentials from Cognito Identity

[jarvislin]

Hi, I followed README document and created account / logged in successfully in sample App. But I got an error in Step 5. when I clicked START MASTER or START VIEWER.

It showed me a dialog with text:

Create client failed with Failed to get credentials from Cognito Identity

I had filled everything in awsconfiguration.json, but still got the same error. Should I put additional code in the sample app's project?

-- and there are the logs:

Hi @jarvislin , as you are able to sign in and see the page with start master/start viewer, I think you have the cognito setup properly. But maybe due to previous trial, some leftover persistence of credential of expired session stays in your app. Click on left-top menu, you will find the Logout option. Try log out and log in again to see if the issue persists.

If logout doesn't help, can you also provide your android device information and OS version so we can see if we can reproduce the issue?

@zhiyua-git I found there are two PoolId in awsconfiguration.json, and they should be different. This issue is solved after I changed the value. Thanks you.
