I expose my userId in the user documents to make it easier for later use. Will this create any issue.

No. Exposing the user UID does not or will not create any threat to your database until and unless you have your firebase rules properly setup.

This is not entirely true. An insecure system could still reveal something about a user given a UID, even if the UID itself doesn't contain any data. – Doug Stevenson Sep 15 '20 at 03:13
