Additional Context

• The session file exists at: ~/.claude/projects/-Users-michael-artz-dev-asset-management/54f512c7-098a-46f7-989d-60fedb59bbd2.jsonl
• The session file is 438 lines long and appears to be valid JSONL
• The session ended with repeated API 404 errors for model claude-3-5-haiku-20241022
• Running claude sessions list also times out (after 2+ minutes)
• The session file contains entries with empty/undefined text fields in some message objects

Observations

The error suggests the CLI is trying to call .trim() on an undefined value when parsing the session file. This may be related to:

1. Sessions that ended with API errors
2. Message entries with missing or undefined text fields
3. Corrupted session state from incomplete API responses

Environment

• Platform: macOS (darwin)
• Installation: Homebrew (/opt/homebrew/lib/node_modules/@anthropic-ai/claude-code/)

Workaround

The session data was successfully recovered by manually parsing the JSONL file with Node.js.
