TL;DR

The most likely fix is to configure the required user settings, specifically the api_url, to resolve the "Missing required user configuration value" error.

Guidance

• Verify that the api_url is correctly set in the user configuration.
• Check the documentation for the correct format and value for the api_url setting.
• Ensure that the user is properly logged in and authenticated before launching with the --bare option.
• Review the error messages for any other missing configuration values or authentication issues.

Example

No code snippet is provided as the issue seems to be related to configuration and authentication.

Notes

The issue seems to be related to missing configuration values and authentication issues. The provided error messages indicate that the api_url is not set, and there are rate limit errors and authentication failures. The content was truncated, so there may be additional error messages or information that could help resolve the issue.

Recommendation

Apply a workaround by configuring the required user settings, specifically the api_url, and ensure proper authentication before launching with the --bare option. This should resolve the "Missing required user configuration value" error and potentially other related issues.
