What's Wrong?

Environment

• Claude Code version: 2.0.1
• OS: Ubuntu (WSL2)
• Node.js version: (node --version 결과)

Problem

claude --resume and claude --continue always return
"No conversations found to resume/continue"

Each attempt creates error-only .jsonl files containing:
API Error: 404 {"type":"error","error":{"type":"not_found_error",
"message":"model: claude-3-5-haiku-20241022"}}

The summary generation process uses a deprecated model,
causing 404 errors. These error files then prevent
resume/continue from finding valid conversations.

Steps to reproduce

1. Run claude and have a conversation
2. Exit normally
3. Run claude --resume → "No conversations found to resume"
4. Check ~/.claude/projects/ → new small .jsonl files with 404 errors

Expected behavior

--resume should list and resume previous conversations.

What Should Happen?

claude --resume should list previous conversations and allow
resuming them. The summary generation should use a currently
available model (e.g., claude-haiku-4-5-20251001) instead of
the deprecated claude-3-5-haiku-20241022. Error-only .jsonl
files should not block conversation discovery for resume/continue.

Error Messages/Logs

Steps to Reproduce

1. Run claude in any project directory and have a conversation
2. Exit the conversation normally
3. Run claude --resume
4. Result: "No conversations found to resume"
5. Check ~/.claude/projects/<project-dir>/
6. New small .jsonl files appear containing only:

{"type":"summary","summary":"API Error: 404 {\"type\":\"error\",
\"error\":{\"type\":\"not_found_error\",
\"message\":\"model: claude-3-5-haiku-20241022\"}}"}

1. Deleting these error files does not help —

running --resume generates them again immediately

1. claude --continue also fails with same issue
2. Only workaround: claude --resume <specific-conversation-id>
