The 1st example with mapping doesn't work

[bz123]

Thanks for all the work you've done but am having an issue with mapping.

This part of the first example doesn't seem to work:
Config.credentials = new CognitoIdentityCredentials({ IdentityPoolId: appConfig.IdentityPoolId, Logins: { [cognito-idp.${appConfig.region}.amazonaws.com/${appConfig.UserPoolId}]: result.getIdToken().getJwtToken() } });

On my online dashboard for that userpool I can't see that specific user being logged in.

Same happens when am trying to map back a facebook access token to generate a JWT token from the session.

Any Ideas?

Are you using react native facebook login to get an access token? The way it works is you need the access token from Facebook sdk and pass that to the Logins array in cognito. Then when credentials is set you'll be able to get a session off the user.

Essentially mimic this:

http://docs.aws.amazon.com/sdk-for-javascript/v2/developer-guide/loading-browser-credentials-cognito.html

The access token comes from Facebook.

To get the session and any other information refer to the amazon cognito identity js sdk for use cases.
