What's Wrong?

Teammate pane crashes in tmux when a permission prompt appears (e.g., a request to read the parent directory ..).

The pane displays the error: `<Box>` can't be nested inside `<Text>` component.

What Should Happen?

The permission prompt should render correctly in the teammate pane without crashing it.

Steps to Reproduce

Prerequisites: WSL, tmux, Claude Code version 2.1.117 or newer.

Relevant settings in ~/.claude/settings.json:

{
  "verbose": true,
  "teammateMode": "auto",
  "tui": "fullscreen",
  "theme": "light",
  "showThinkingSummaries": true
}
  1. Ask the teamlead (orchestrator) to create a team and a teammate.
  2. Ask the teamlead (or the teammate directly) to read the parent directory (..).
  3. In the teamlead pane: a permission request appears.
  4. In the teammate pane: the error message appears and the pane crashes.

Last Working Version

2.1.116

Additional Information

Version 2.1.116 does not have this bug. The crash reproduces consistently on 2.1.117, 2.1.118, and 2.1.119.

extent analysis

TL;DR

Downgrade to version 2.1.116 to avoid the teammate pane crash when a permission prompt appears.

Guidance

  • The error message suggests a rendering issue with the <Box> and <Text> components, which may be related to changes introduced in version 2.1.117.
  • Verify that the issue is resolved by downgrading to version 2.1.116 and reproducing the steps to reproduce.
  • Check the ~/.claude/settings.json file to ensure that the settings are not contributing to the issue, although the provided settings do not seem to be directly related to the rendering issue.
  • If downgrading is not feasible, consider reaching out to the development team for a patch or fix for the rendering issue in versions 2.1.117 and later.

Example

No code snippet is provided as the issue seems to be related to a specific version of the software rather than a code error.

Notes

The fix is based on the information provided that version 2.1.116 does not have this bug, and the issue reproduces consistently on versions 2.1.117 and later. However, this may not be a long-term solution, and a proper fix for the rendering issue should be investigated.

Recommendation

Apply workaround: Downgrade to version 2.1.116. This is because the issue is consistently reproducible on versions 2.1.117 and later, and downgrading to 2.1.116 has been confirmed to resolve the issue.
