error: unhandled chunk type
Having the same error on this session https://opencode.ai/s/Otz01W1E
I've never used opencode before, I just installed it for the first time now, logged in to claude with the MAX sub, and all I get is this. Removing the cache didn't work for me.
Not sure if it's an issue with the sub integration, but can't get it to work unfortunetly.

This issue might be a duplicate of existing issues. Please check:
- #205: Same exact error message and symptoms ("error: unhandled chunk type"). This issue was actually created from a comment in #205. The original reporter in #205 resolved it by clearing cache with
rm -rf ~/.cache/opencode, though this solution didn't work for the current reporter.
Feel free to ignore if none of these address your specific case.

@limoragni Could you return what you get when you run this command? opencode run hello --print-logs. Idk if there is a way to choose a specific model when running this, best I can say is to make sure the last used/selected model is the sonnet-4 one that has the issue.
See the output below. Not sure if becuase running this, but after running it I open opencode again and it worked.
