Environment:

  • Claude Code CLI on Windows 11 Pro
  • Model: claude-opus-4-6
  • Date: 2026-02-25

Issue:
Getting repeated 500 Internal Server Errors mid-session. The errors occur during normal tool usage, not during heavy processing.

API Error: 500 {"type":"error","error":{"type":"api_error","message":"Internal server error"},"request_id":"req_011CYVB4LhMaWAT6eQikcf3N"}

The same request_id appears twice, suggesting the retry also failed with the same error.

Steps to reproduce:

  1. Start Claude Code session
  2. Execute a tool call (Glob succeeds)
  3. Next response triggers 500

Expected: Normal response
Actual: 500 Internal Server Error, repeated on retry

Request ID: req_011CYVB4LhMaWAT6eQikcf3N

I keep encountering the same error message, and it's extremely frustrating. This ongoing issue is making it impossible for me to complete my work effectively.

Cut the marks into small dots using the agents. This significantly reduces error.

I don't have any errors at the moment. Let's pray.

I didn't say anything. Hahaha.

But the agents still work, I can work.
