26A AI Agent – Malformed REST GET query when using input variables

Summary:

When testing an AI Agent Studio Agent Team Workflow in the AI Agent Studio Lab, the agent intermittently fails to form the query string (q) for an External REST GET call.

• The agent sometimes constructs the query string successfully, and the GET call executes without issues, but failures occur more often than successes.
• Agent Node block traces indicate that the agent forms the query string but does not replace the input variable placeholders in the GET endpoint resource path.
• Using literal values in the agent prompt works consistently, confirming that the issue is not with variable resolution—the input bindings themselves are successfully resolved.
