What's Wrong?

⎿ API Error: 500 {"type":"error","error":{"type":"api_error","message":"Internal server error"},"request_id":null}

What Should Happen?

Since this morning, whether I'm using IntelliJ IDEA or Visual Studio Code, Claude starts a task but never finishes it completely. Instead, it stops and shows this error message:

⎿ API Error: 500 {"type":"error","error":{"type":"api_error","message":"Internal server error"},"request_id":null}

This means that there’s an internal server error on Claude’s side (a “500” error). It’s not an issue with IntelliJ IDEA or VS Code — it indicates that Claude’s API (the backend service it connects to) is having a problem processing the request.

In short: Claude is failing to complete the request due to a temporary server-side issue, not because of your local setup or editor configuration.

I have encountered it today as well, what is strange is that when I switch models it works:

login ⎿ API Error: 500 {"type":"error","error":{"type":"api_error","message":"Internal server error"},"request_id":"req_011CVT2B3efKEUQRB5JqeV4B"}

even login and logout is giving 500!!

Update :

API Error: 500 {"type":"error","error":{"type":"api_error","message":"Internal server error"}, "request_id":"req_011CVT2B3efKEUQRB5JqeV4B"} .

Steps / env: – macOS (Apple Silicon) – Claude Code 2.0.50 – Originally installed via the old local ~/.claude/local/claude setup – login had been working for months, then suddenly started returning 500 without any change on my side

What I did: – Removed the old local install: rm -rf ~/.claude – Cleared the alias in my shell (unalias claude) – Reinstalled via the new official installer: curl -fsSL https://claude.ai/install.sh | bash – New binary path is now: ~/.local/bin/claude

After that, claude starts normally. Did a fresh auth too. Not sure if the fix was the reinstall itself or a backend recovery around the same time, but leaving this here in case it helps correlate and unblocking :)

faced the same issue just now. Waited a few minutes and retried a few times. Did not help. Even after an hour, the session gave me still the same error. However, closing the session and starting claude again with the -r resume command worked and after that, no more errors
