Troubleshooting Dust App Issue with HR Tool Access

·Jun 30, 2025 01:43 PM·

Hello, One of my agents uses a Dust App that retrieves data from our HR tool. It used to function properly, but it no longer works and I can’t figure out why. When I run the App directly, it returns the expected results, so I don’t believe the problem lies there. However, when the agent tries to use the same App, it reports that the tool is unavailable. I’ve even tried recreating the App from scratch, but the issue persists. It’s worth noting that the agent successfully uses other Dust Apps without any problems. It seems that, for some reason, the agent fails to trigger this particular App, even though it appears in the list of available tools. Has anyone encountered something similar or can offer some guidance?

Hi Nicolas, what do you see when you click on "Tools inspection" ?

I can see that the agent uses all the tools at its disposal, but not this specific app. I specified in the prompt that the agent must use this app, but no dice. I asked the agent itself what’s happening, he explains that he receives this error :
“An error occurred while listing the available tools for get_lucca_axissections. Tools from this server are not available for this message.”

Can you send the Dust app details to support@dust.tt? We're going to need to see some real data if we want to investigate. Please send your conversation URL so we can take a look at your agent and instructions 🙂
