Description

I have Taskmaster setup in Cursor on my mac and I use Claude Code inside of cursor.
Whenever I try to create a task it fails to create a task saying that

✖ AI generation failed
     Error: Claude Code API error during object generation: Claude Code process 
     exited with code 1
     Error adding task: Claude Code API error during object generation: Claude 
     Code process exited with code 1

This behavior is present wether I'm creating the task in Terminal or Claude Code Chat.

I've tried to switching the models to something else and back to Claude Code Opus, but that doesn't work.

I think (no idea) that Task Master hasn't properly authenticated with Claude Code API but I don't know how to trigger that Oauth browser flow again (I think that's how Taskmaster did it back in v.19)

Screenshots or Logs

Environment

Task Master version: v21
Node.js version: 15.x
Operating system: Mac OS
IDE (if applicable): Cursor
