Logging
Section titled “Logging”Debugging UI errors
Section titled “Debugging UI errors”When parts of the page fail to load or an error banner indicating something failed to load is visible, you can check the requests made by the browser to see the exact error.
Many of the asynchronous requests are GraphQL requests to /api/graphql. These requests will have a x-gitlab-feature-category header that can help identify the team responsible.
GraphQL requests can return a 200 response code but have errors in the response body. These can be found in the top-level errors key in the response JSON.
