FWIW, changing the model helped me. Was using Opus, but changing to Sonnet got rid of the error.

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.
