Claude Code integration getting "Failed to authenticate" error

Describe the issue

In a new repository, which just contains an empty README.md file, I started on new codegen session and provided a simple prompt. The response was:

Failed to authenticate. API Error: 401 {"type":"error","error":{"type":"authentication_error","message":"OAuth token has expired. Please obtain a new token or refresh your existing token."},"request_id":"req_011CXzd54XhtHRVhMfVCVq5J"}
Claude exited with non 0 error code

claude appeared to be running fine. I started it and it showed me a blinking cursor. I tried running a prompt in claude and got the same error message, but it included a tidbit that I needed to run /login. After I ran /login in the claude session, then the GitButler Claude Code integration started working as expected.

I think it would be helpful to trap this response from Claude Code and direct folks to login or provide some kind of preflight check that makes sure that claude can respond to a simple prompt.

Thanks a lot for reporting!

I also ran into auth-related issues and GB wasn't able to provide guidance.
Let me CC @Caleb-T-Owens in case this is a quick fix.

Thanks for tagging me @Byron,

The app used to inject its own tidbit about running the CLI once to follow the login flow, but it looks like something on either CC's side or ours may have changed here. @mtsgrd, might you be able to take a look?

Yess, thanks, I'll take a look at this.

Thanks for reporting this. The in-app Claude Code integration was removed in #13850, and that change shipped in 0.20.0; agent workflows now use the but CLI and agent skill instead.

Since this authentication path no longer exists, I'm closing this one. Let me know if I missed a current equivalent.
