extent analysis

TL;DR

The error "Invalid configuration: invalid type: map, expected a sequence in 'hooks'" suggests a configuration issue that can be resolved by checking the 'hooks' configuration in the project settings.

Guidance

  • Review the project directory configuration to ensure the 'hooks' setting is correctly defined as a sequence, not a map.
  • Verify that the 'hooks' configuration is consistent across all projects, as the issue only occurs with certain projects.
  • Check the Codex App documentation for specific guidance on configuring 'hooks' for the Pro subscription on Darwin platforms.
  • If the issue persists, try resetting the project configuration to its default state to isolate the problem.

Notes

The root cause of the issue is likely a misconfigured 'hooks' setting, but without more information about the project configuration, it's difficult to provide a more specific solution.

Recommendation

Apply workaround: Check and correct the 'hooks' configuration in the project settings, as this is the most likely cause of the error and can be resolved without upgrading or modifying the Codex App version.
