}

And screenshoot from debugger from place, that is making issue

Reproduction

1. Try to login with user credentials that have 'user_metadata'
2. 'onSuccess' callback method in 'WebAuthProvider.login' call 'credentials.user'

I just believe, that or data returned by server are not in correct format, or parser is not working in correct way

Additional context

Issue is similar to:
#196
and have something in common with:
#429

Auth0.Android version

2.10.2

Android version(s)

14 (I believe, it doesn't matter)

@gier3k running the JSON you provided through a JSON formatter seems to tell there is an issue in the format of the JSON.

Can you verify that a properly formatted JSON is provided so that correct Key, Value pairs can be extracted.

@poovamraj
I can confirm, that this, what app is getting is not properly formatted JSON (at least not for schema, that is expected, so that in 'user_metada' is provided map, and not String, that is looking like map).
I can also confirm, that if I inject little modified base64 json string:

}

then user object is properly parsed and I don't have issues with it.

So now there is question (as I don't know) - this not proper json is coming from fault of AUth0 servers or from our company/organization code/servers

[poovamraj]

There is a good chance it is coming from organisation code. Can you verify this one.

Since this is not an issue on the SDK side. We would like to close this issue for now. If you have more doubts you can comment here and we can reopen this issue.
