Recommended action: Set CLAUDE_CODE_STREAM_CLOSE_TIMEOUT (milliseconds) higher, and reduce startup work (pre-install MCP server packages instead of npx downloads).
Option: Set CLAUDE_CODE_STREAM_CLOSE_TIMEOUT (milliseconds) higher, and reduce startup work (pre-install MCP server packages instead of npx downloads). [evidence: official_recommended_action]
Applies when: ClaudeSDKClient/query() with slow-starting MCP servers or heavy plugin/hooks setup
Steps:
1. export CLAUDE_CODE_STREAM_CLOSE_TIMEOUT=180000
2. Pre-install MCP servers used via npx/uvx
3. Check CLI stderr for the stalled step
Expected: The error no longer appears.
Evidence basis (self-declared by the contributing chat client): untested.
