It would help a lot if the exception is shown instead on the page when this happens.</p> <h4 id="summary-steps-reproduce">Steps to reproduce</h4> <p>Create a tool or change a tool to throw and exception.<br> Create an agent with that tool and a prompt to always runt this tool.<br> Run the agent in AI Agent Explorer.</p> <h3 id="summary-proposed-resolution">Proposed resolution</h3> <p>Add a try catch to the whole runner.<br> Return the message and the stacktrace as ajax output.</p>
