[BUG] Constantly Getting API Error: 500
Preflight Checklist
- [x] I have searched existing issues and this hasn't been reported yet
- [x] This is a single bug report (please file separate reports for different bugs)
- [x] I am using the latest version of Claude Code
What's Wrong?
I am getting error below for nearly every prompt.
- Tried plan mode on and off.
- Cleared session
- Closed terminal (ghostty) and opened again
- It seems like when files are not involved in the session errors don't occur.
What Should Happen?
Claude should run prompts successfully
Error Messages/Logs
API Error: 500 {"type":"error","error":{"type":"api_error","message":"Internal server error"},"request_id":null}
Steps to Reproduce
The prompt is use:
You are an expert project manager. Your task is to update Duration calculation of "Phase 2: Design" in @"Project Management/Project_Timeline_Estimates.md".
Detailed task descriptions and info is in @"Project Management/WBS.csv".
When calculating duration of a phase you should consider effort shared by the roles. For example implementing login screen task can have total effort of 20 hours but if 12 hours of
BE dev 8 hours of FE dev is involved and it is possible them to work in parallel in this specific task you can estimate the duration lets say 13 hours. Assume that team has high
collaboration capacity, maybe it is impossible to total parallelization but members can work together efficiently.
Also you can find team configuration in @"Project Management/Project_Timeline_Estimates.md" too to understand resources.

Same, it's pretty frequent.
And as per usual, the status page shows everything is just fine:

Clearly, it's not fine:

I've been getting this on and off for the last 24 hours. Very irritating. Sometimes closing VS Code and re-opening works - and sometimes it doesn't.

Hi folks, thanks for reporting this. These 500 errors were caused by transient API outages on the Anthropic side — not a bug in Claude Code itself. The API is currently healthy, so I'm closing this out. If you're still experiencing 500 errors, you can check the API status at https://status.anthropic.com, and if the issue persists while the status page is green, please open a new issue with your request ID and we'll investigate.
