[ASK] Is it possible to getSession with only `refreshToken` value ?

[derohimat]

In my case, I want to integrate a deeplink for login with refreshToken value.

For example https://example.com/login?refreshToken=XYZ

And is it possible to send empty username into CognitoUser class ?

      final cognitoUser = CognitoUser('', Config.userPool);
      final cognitoRefreshToken = CognitoRefreshToken(refreshToken);
      final session = await cognitoUser.refreshSession(cognitoRefreshToken);

I have try but get this error.

@derohimat I don't think AWS API allows it. At least JS lib doesn't allow - https://github.com/aws-amplify/amplify-js/blob/main/packages/amazon-cognito-identity-js/src/CognitoUser.js#L1386

Solved, just put empty username and put refresh token here.

Example

          final cognitoUser = CognitoUser('', Config.userPool);
          final cognitoRefreshToken = CognitoRefreshToken(refreshToken);
          final newSession = await cognitoUser.refreshSession(cognitoRefreshToken);
