Hi @Ankit Raibole ,
Thanks for reaching out.
The reason you are not getting any specific error is that there's some error state being encountered when AAD's SCIM client sends a request, and the response may not be compliant with the SCIM standard - for example, particularly bad issues sometimes lead to errors at the HTTP layer before it gets to SCIM, and it may be the HTTP service (IIS, etc..) is throwing a 500 Internal Server Error or something similar without following the SCIM standard's approach to this error.
Could you please confirm if you have added new attribute mapping or any changes you made to provision the user?
Thanks,
Shweta
