@Rajat-TVSM , The error usually suggests incompatibility between your request payload and what the model expects.

However, if you have verified that the same payload no longer reproduces the issue, it will be challenging to identify the root cause. You can wait to see if the issue occurs more frequently, which may help identify a pattern.

That message is the generic model-serving “bad request” wrapper we return when a predict operation fails or the request doesn’t match the model’s expected input. The quickest way forward is to validate your payload against the model signature and inspect the endpoint’s 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.
