**Scenario** : A server-side error occurs in NAV while processing a request, such as attempting to create a record with invalid data.  
 **Error Message** : `Server returned a HTTP error code (not 200 OK): 500 Internal Server Error`.  
**Cause** :

1. Invalid data in the request payload (e.g., malformed email address).
2. Unhandled exception in NAV code.

**Resolution** :

1. **Review the NAV Logs** :
  - Check the Event Viewer or Debug logs on the NAV server for detailed error information.

2. **Validate Data** :
  - Ensure all input data conforms to NAV’s validation rules.

3. **Test with Minimal Payload** :
  - Filter on a single record to isolate the root cause.
