Troubleshooting Dust App Tool Attachment Errors with Agents

·

Hi - I’m getting an error whenever I attach a specific Dust app tool to an agent:ERROR: Failed to build the specification for action CUhcdRXmbX, (code: build_spec_error). The app itself is running successfully when built and tested, and the agent doesn’t return an error when this tool is removed. Any idea on how to trouble shoot?

Is it only when adding one of the 3 attached dust apps?

Ok, possible to send a screenshot of the conf of this dust app? If there's anything sensitive you can send in private

I ran into the same issue. By simplifying my app, I found that this happens anytime the dataset has a parameter of type json. Attaching screenshots from my trivial scenario, which just consists of an INPUT block and nothing else. CJ did you also have a json param?Alban could it be that json params are generally broken?

I opened https://github.com/dust-tt/dust/issues/11668 for tracking.

Hi, yeah David Ebbo you got it, I believe JSON is generally quite broken in Dust apps

I've moved your card to escalate it, so you might have lost access to it David Ebbo

Thanks Alban. I was actually still able to see and update the github issue.
