Bug Description
Claude Code crashes with TypeError: Cannot read properties of undefined (reading 'message') when user rejects a permission-required tool use (such as Bash commands) within the Task tool via the interactive prompt.
Steps to Reproduce
- Start Claude Code with
claude - Enter "Please run rm no-exists-file in task tool"
- Task tool attempts to use Bash tool (which requires permission)
- When the tool use permission prompt appears, press 3 or choose "No, and tell Claude what to do differently (esc)"
- CLI crashes with TypeError
Expected Behavior
The CLI should gracefully handle the tool rejection and either:
- Show a message that the tool use was rejected
- Ask for alternative instructions
- Continue the conversation without crashing
Actual Behavior
The CLI crashes with the following error:
TypeError: Cannot read properties of undefined (reading 'message')

Additional Context
The error appears to be in the renderToolUseRejectedMessage function when trying to access the message property of an undefined object during array filtering. This suggests there's a null/undefined handling issue in the tool rejection flow.

This seems to occur only when using Claude hooks. The only hook I'm using is the following:
{ "model": "sonnet", "hooks": { "PreToolUse": [ { "matcher": "", "hooks": [ { "type": "command", "command": "jq '.' >> /tmp/claude_hooks.jsonl" } ] } ] } }takahirom commentedon Aug 3, 2025
I think this has been fixed. If you have the same problem. Let me know.
