Hello @siripurapurahul ,
Apologies for the delay in our update. Please refer to the following post:

JWT URL usually ends with users/sts or /sts or /jwt - but it totally depends on the developer/ implementor how you want to configure the endpoint. The right end-point needs to be used, and it just needs to respond with the right JWT token.
This should resolve the error.
