Description copied from interface: DataFetcherExceptionResolver

Resolve the given exception and return the error(s) to add to the response.

Implementations can use GraphqlErrorBuilder.newError(DataFetchingEnvironment) to create an error with the coordinates of the target field, and use ErrorType to specify a category for the error.

Specified by:

resolveException in interface DataFetcherExceptionResolver

Parameters:

exception - the exception to resolve

env - the environment for the invoked DataFetcher

Returns:

a Mono with errors to add to the GraphQL response; if the Mono completes with an empty List, the exception is resolved without any errors added to the response; if the Mono completes empty, without emitting a List, the exception remains unresolved and gives other resolvers a chance.
