Most likely, one of the agent tools returned a null or invalid response, and the agent failed while building the next step because required fields were missing. Check the tool's input/output schema, ensure required fields are always returned, and guard against null collections.

HI [mention:9861aef97eb2483a8b76175d9eda1e37:e9ed411860ed4f2ba0265705b8793d05] 
In these agend I am only using one record as the tool. Where No input variable are passed.

Your Query Record tool might  returning null (likely empty result set or a required record field is null).
Ensure the record has data and all required schema fields return non-null values ; return {} instead of null for empty results.
