Bug Report
Description
Receiving repeated HTTP 500 Internal Server Error responses from the Claude API during an active Claude Code session. The session becomes completely unresponsive — both the initial request and retry attempts return the same 500 error.
Error Details
API Error: 500 {"type":"error","error":{"type":"api_error","message":"Internal server error"}}
Two consecutive request IDs observed:
req_011Ca21czupg8JxJf17zRhUBreq_011Ca21hjUGzdQZ9CrsB2y1k
Environment
- Claude Code version: v2.1.104
- Model: Opus 4.6 (1M context)
- Plan: Claude Max
- OS: macOS (Darwin 25.1.0)
- Context usage at time of error: ~55% of context window
Steps to Reproduce
- Working in an active Claude Code session with moderate context usage (~55%)
- Session was performing code edits (R visualization code) and file operations
- After completing a tool call (Bash command with no output), the API returned 500
- Typing "continue" also returned 500
- Session became stuck — no further interaction possible
Expected Behavior
The API should return a valid response or a retryable error with a clear message.
Actual Behavior
Repeated 500 Internal Server Error with no recovery. The session must be abandoned and restarted, losing the current conversation context.
Impact
- Loss of active work session context
- Requires re-establishing full project context in a new session
- Token cost of the abandoned session is wasted
Additional Context
This occurred during a long-running session with multiple file reads, code edits, and bash executions. The session was not at the context limit (approximately 55% usage). No unusual operations were being performed at the time of the error.
