That message is the generic model-serving โbad requestโ wrapper we return when a predict operation fails or the request doesnโt match the modelโs expected input. The quickest way forward is to validate your payload against the model signature and inspect the endpointโs inference logs to pinpoint the failure.
As you have mentioned that this is an Agent Serving endpoint, if you had served the model via the deploy() function, inference tables are enabled automatically and store payloads.
