REST_SERVER_NOT_FOUND

REST_SERVER_NOT_FOUND

Error message

Resource not found on REST server. Request: 

What it means

Thrown by the REST function-namespace executor's exception handler when the HTTP call for a function lookup completes with an error and the server reports the requested resource as absent (404-class outcome). The failing request is appended so the missing function/endpoint can be identified.

Solutions

1. Verify the function exists in the namespace at that REST endpoint
2. Check function name and version in the invocation
3. Re-register the missing function
