  • Shell: zsh

extent analysis

TL;DR

The issue is likely due to a JavaScript runtime error caused by an undefined function, and checking the claude code version and dependencies may help resolve the issue.

Guidance

  • Verify that the claude version 2.1.119 is compatible with the current environment and dependencies.
  • Check the entrypoints/cli.js file for any syntax errors or missing function definitions, specifically around line 9251.
  • Investigate if there are any known issues or updates available for the claude version 2.1.119 that may address the JavaScript runtime error.
  • Consider reaching out to the claude development team or community for further assistance, as the error message suggests a potential issue with the claude codebase.

Notes

The provided information suggests a potential issue with the claude codebase, but without more context or details about the claude project, it's difficult to provide a more specific solution.

Recommendation
