My own log file in the script is never created indicating its not being called. I confirmed the command works though.

TL;DR

The otelHeadersHelper script is not being executed, likely due to incorrect configuration or environment settings.

Guidance

  • Verify that the otelHeadersHelper path in the settings file is correct and the script has execute permissions.
  • Check the environment variables set in the settings file, such as CLAUDE_CODE_OTEL_HEADERS_HELPER_DEBOUNCE_MS, to ensure they are not preventing the script from running.
  • Add logging or debugging statements to the otelHeadersHelper script to confirm it is being called and to identify any potential issues.
  • Review the Claude Code documentation to ensure that the otelHeadersHelper configuration is correct and compatible with version 2.1.81.

Example

No code snippet is provided as the issue is likely related to configuration or environment settings.

Notes

The lack of error messages or logs makes it difficult to determine the root cause of the issue. Additional debugging or logging may be necessary to identify the problem.

Recommendation

Apply workaround: Verify the otelHeadersHelper configuration and environment settings to ensure they are correct and compatible with the Claude Code version being used.
