Hey @SinarSaktiInternasional , thanks for opening the issue.

The TAVILY_KEY is a red herring. I'll fix it shortly. It doesn't affect the execution, it just means that the search tool (not used at this time) isn't going to work unless you set the environment variable. If you aren't planning on using the web search tool then don't worry about it.

In your case, I think the problem is about not setting up the Perplexity key. Please take a look here: https://laszukdawid.github.io/terminal-agent/providers/#perplexity. Did you set up PERPLEXITY_KEY env variable? Behind the scenes, Terminal Agent uses Perplexity API (https://docs.perplexity.ai/home) if that provider is selected. They've been rather "inconsistent" with their APIs (and models) so I haven't tested them extensively. Will do it soon.

Come to think of it, it there was an issue with the key then you'd see an error stating to provide the key. In your case, the problem was that the response was empty. I have patched the handler so that it checks for empty response and provides a better error; however, it isn't clear to me when we'd get an empty response.

Any chance you could share a bit more about how you ended up with that error?
