Exceptions not working as expected with Directive Wiring #79
Description
Describe the bug
I'm trying to connect kotlin, spring for graphql, and the validation feature, but when I add the directive wiring, the exceptions thrown in the service layer are not being displayed correctly.
Config:
@Configuration
class GraphQLConfig {
@Bean
fun runtimeWiringConfigurer(): RuntimeWiringConfigurer {
val validationRules = ValidationRules.newValidationRules()
.onValidationErrorStrategy(OnValidationErrorStrategy.RETURN_NULL)
.build()
val schemaWiring = ValidationSchemaWiring(validationRules)
return RuntimeWiringConfigurer { builder: RuntimeWiring.Builder ->
builder.directiveWiring(schemaWiring).build()
}
}
}
Controller:
@MutationMapping
fun createCourse(
@Arguments createCourseDto: CreateCourseDto
): CourseDto {
throw RuntimeException("exception from controller")
}
Graphql:
directive @NotBlank(message : String! = "graphql.validation.NotBlank.message") on ARGUMENT_DEFINITION | INPUT_FIELD_DEFINITION
createCourse(
name: String! @NotBlank
): Course
type Course {
id: ID
name: String
}
When I call this endpoint, the result is an empty object, in the background, an exception is being thrown (check the controller snippet above)
{
"data": {
"createCourse": {
"id": null,
"name": null
}
}
}
But If I remove the directive wiring config:
//@Configuration
//class GraphQLConfig {
//
// @Bean
// fun runtimeWiringConfigurer(): RuntimeWiringConfigurer {
// val validationRules = ValidationRules.newValidationRules()
// .onValidationErrorStrategy(OnValidationErrorStrategy.RETURN_NULL)
// .build()
// val schemaWiring = ValidationSchemaWiring(validationRules)
//
// return RuntimeWiringConfigurer { builder: RuntimeWiring.Builder ->
// builder.directiveWiring(schemaWiring).build()
// }
// }
//}
I do get the exception as usual:
{
"errors": [
{
"message": "INTERNAL_ERROR for a9883b45-f615-258a-4f7a-bda5b432d485",
"locations": [
{
"line": 2,
"column": 3
}
],
"path": [
"createCourse"
],
"extensions": {
"classification": "INTERNAL_ERROR"
}
}
],
"data": {
"createCourse": null
}
}
Is it something wrong with the code, or could this be a bug?
