@gauravmahlawat, the problem is here: https://git.drupalcode.org/project/do_username/-/blob/2.x/src/DOUserInfoRetriever.php?ref_type=heads#L64. We are calling ->current() directly without any validation.

I think we should use current() instead but that function seems to have been deprecated for objects. We should explore a better way to call ->current() here or wrap it in a call to ->valid().

Thank you @hussainweb, I will check and work on it.
