API Error: InvalidHTTPResponse

[JulyanZhu]

Hi, thank you for your project. I can get normal response when sending simple prompt like "Hello".

But when I started coding task, the task always fail halfway and get these error:

API Error: InvalidHTTPResponse fetching "https://api.deepseek.com/anthropic/v1/messages?beta=true". For more information, pass `verbose: true` in the
     second argument to fetch()

And another:

API Error: The socket connection was closed unexpectedly. For more information, pass `verbose: true` in the second argument to fetch()

Update:
I asked the agent to continue task, it proceeded and I can see the proper output.
But when generating, it failed halfway, repalced all the white character generated with this error message:

Update:
I found this in the ~/.claude/projects/....jsonl, may help:
