@ExceptionHandler not getting called

[AnandMandhre]

Hello Guys,

I have a problem trying to configure @ExceptionHandler with my springboot application. In my application exceptions get handled inside SimpleDataFetcherExceptionHandler despite configuring and @component with @ExceptionHandler methods for various exceptions.

I have set the properties correctly and followed the disucssion on link mentioned below.
graphql.servlet.exception-handlers-enabled=true

[https://github.com//issues/384]

It could be that other jar file in my pom are causing it. I have included spring cloud stream and kafka binder recently.

How can check if my exception handler got configured correctly (maybe via GraphQLWebAutoConfiguration or GraphQLErrorStartupListener)?

Is there a way to set it manually using @configuration approach ?

Thanks

Debugging further and after setting debuging on. I noticed following logs

DEBUG g.k.s.e.GraphQLErrorHandlerFactory - Handle GraphQL errors using exception handlers defined in 0 custom factories

I had expected size of custom factories to be 1. Having an object of type ReflectiveGraphQLErrorFactory containing my handler (bean).

I came with idea to create GraphQLErrorFromExceptionHandler with List, list could have contained my customerrorhandler but class is not visible out of the library.... so thats that. Running out of ideas :(

Any suggestions group ?

Have you resolved this issue?

No, I had to work around it. Using

@component
public class CustomErrorHandler implements GraphQLErrorHandler
@OverRide
public List processErrors(List errors) {
creating and returning GenericGraphQLError object with my custom message in it.

Are you using the latest version of this library? There was a problem with the exception handler for a while that went unnoticed in earlier versions.

Did you add the value parameter to the @ExceptionHandler annotation? The implementation used here needs that value instead of being able to determine the type to use based on the parameter.

Does your annotated method have a return type of GraphQLError or a List<GraphQLError>? That's required to be taken into consideration.
