A bug in a browser automation tool caused it to return the literal string "[object Promise]" instead of actual webpage content. This occurred because the tool used AppleScript to execute JavaScript, and the JavaScript code contained an `await` call within an asynchronous function. AppleScript, being synchronous, could not handle the asynchronous operation and instead stringified the pending Promise object, returning it as the result. This silent failure went unnoticed by the AI agent using the tool, leading to incorrect conclusions and propagating errors. AI
