Issue related to userId not reflecting at upstream side

Hi All,
The issue is for the API routes we have configured at Kong Gateway side we are not getting the expected userId.Only for 1 route the userid is coming as expected and not reflecting for other routes.
We replicated the same configuration for other routes as the working route but still the issue persists.

Note:The userId could only be checked at client end at upstream level.
We are not having access

There is no http error response only issue we are not getting the expected userId the incorrect userId is reflecting at enduser side

Can you share your config and a test request and response (expected)?

Now the issue is resolved
