Fix InternalServerError

✅ Solution

The "InternalServerError" in hasura-auth often arises from unexpected responses (like empty or non-JSON) from external APIs it relies on for authentication or user management. To fix this, implement robust error handling, specifically checking for and gracefully handling 204 No Content responses or invalid JSON from upstream services by either returning a valid default response or retrying with exponential backoff. Additionally, add logging to capture the exact problematic response for debugging.
