TL;DR

Remove the Bearer prefix from the Authorization header to resolve the GraphQL operation failure.

Guidance

• Verify the Authorization header format in the API request to ensure it does not include the Bearer prefix.
• Check the API documentation to confirm the correct format for the Authorization header.
• Review the error message to identify any other potential issues with the API request.
• Consider updating the code to handle API errors and exceptions more robustly.

Example

No code snippet is provided as the issue does not include sufficient code context.

Notes

The provided error message suggests a specific issue with the Authorization header, but the root cause of the duplicated terminal output is unclear and may require further investigation.

Recommendation

Apply workaround: Remove the Bearer prefix from the Authorization header, as this is the most direct solution to the identified error.
