TL;DR

Check and configure the api_url value in the user configuration to resolve the "Missing required user configuration value" error.

Guidance

• Review the user configuration for the api_url value, ensuring it is correctly set and validated before use.
• Verify that the api_url is properly formatted and points to a valid API endpoint.
• Check the documentation for the @anthropic-ai/claude-code package to understand the required format and any specific validation rules for the api_url configuration value.
• Consider adding validation checks in the code to handle missing or invalid api_url values before attempting to use them.

Example

No explicit code example is provided due to the lack of specific code context in the issue, but ensuring api_url is set before use is crucial:

// Pseudo-example of checking api_url before use
if (!api_url) {
  throw new Error("Missing required user configuration value: api_url");
}

Notes

The exact method of configuring api_url depends on how the @anthropic-ai/claude-code package expects user configuration to be provided, which is not specified in the issue.

Recommendation

Apply workaround by configuring the api_url correctly, as the issue seems to stem from a missing configuration value rather than a version-specific bug that would require an upgrade.
