User not found with ID: {user_id}

Error message

User not found with ID: {user_id}

What it means

_check_user_exists performs find_unique on LiteLLM_UserTable by user_id and gets None: the SCIM caller addressed a user id that does not exist. Raised as 404 so SCIM clients get the standard not-found semantics.
