Failed to AWSMobileClient.getCredentials

[ihdream72]

Hi~

I think I did well according to the guide. I can actually verify user authentication in aws-cognito-console.

but when i try to connect (press start maste/viewer in 2 mobile phone) after "Signaling connect" Toast message, Phone screen was changed 2-camera view. But Local-View only displayed, Remote-View has back screen

I think this problem cause by fail to getCredentials() so can not create AWSKinesisVideoClient.

• Test Phone : Galaxy Note9/10 - Android 10

Can you check my AWSConfiguration.Json File ?

{ "Version": "1.0", "CredentialsProvider": { "CognitoIdentity": { "Default": { "PoolId": "us-east-2:4456b8ff-f34e-485b-86b1-xxxxxxxxcxccc", "Region": "us-east-2" } } }, "IdentityManager": { "Default": {} }, "CognitoUserPool": { "Default": çxxxxxccxxxxcccxcp4rf4jq3ub3cou7o4", "AppClientId": "5e9ok6hk6tb2sqxcccccccxxxxx3f", "PoolId": "us-east-2_pxxxxcccH", "Region": "us-east-2" } } }

Please Help me~~
