Error Running Dust App Agent: Invalid Request with Anthropics API

Hello 🙂 I'm trying to run an agent that uses a Dust App (nothing fancy, a simple input/curl/output) but I'm faced with this error message:

ERROR: Error running agent: Error querying `anthropic:claude-3-5-sonnet-20241022`: error=[model_error(retryable=, request_id=req_011CNTb46CK72RMy8BPvXJeufalse)] AnthropicError: [invalid_request_error] messages: at least one message is required (code: multi_actions_error)

If you look at your App's logs, and choose 'API' (as opposed to Design), is your App even getting called when that happens? And if it is, is it doing what you expect based on the logs?

Last time someone saw that, it was possibly a Claude issue. See https://dustcommunity.slack.com/archives/C06SHT0F20G/p1738640347688349 But not sure if that's what's going on here. Will need a Dust expert! 😅

Luc Lagrange can you try using GPT4?

great ! let's use gpt4 for now, I'll forward the thread to the team just in case the problem is on dust's side and not on anthropic's side 👌
