GraphQL errors can be attributed to one specific phase of the request lifecycle, distinguishing between validation and execution errors, which have different implications for client-side tooling. Validation errors are typically user-facing, while some execution errors may contain only limited information by design. When reporting errors, GraphQL helps to leverage the strict API schema to reconstruct a failing case relatively quickly based on request and response details. An error handling implementation using Apollo Server and Node.js connected to Sentry can be used to report errors with additional context, including operation type, query, variables, and user input. This allows for filtering and inspection of reported events in Sentry, enabling better investigation and troubleshooting of client-side opaque request failures.
