You should review the following items:
Check the request origin:
Ensure you're making the request from the intended source. Verify if the request is originating from the expected location.
Payload mismatch:
Confirm that the payload sent in the POST request aligns with the format expected by the model. Ensure consistency between the model's input requirements and the actual payload in the request.
Serving mode UI:
If using the Serving mode UI with sample data, investigate whether the model functions correctly or throws an error. This may provide insights into potential issues related to the data or the serving environment.
Multi-model issue:
If your are using multiple models in one (multi-model), package them into a single model statically, rather than dynamically loading models from the registry. This adjustment may resolve issues associated with the error.
