Custom Error Handling in GraphQL
Implement custom exception handling and format error responses according to GraphQL best practices.
Understanding GraphQL Errors
When something goes wrong in a GraphQL operation, the server typically returns an errors array in the response. This array contains objects describing what went wrong.
By default, these error messages can be generic or even expose sensitive internal details like stack traces, which isn't ideal for production APIs.
Spring GraphQL's Default Behavior
Out-of-the-box, Spring GraphQL often maps Java exceptions (like RuntimeException) thrown by your data fetchers into a standard DataFetchingException. While functional, this default behavior might not provide the specific, user-friendly details your clients need.
