Class NonNullableFieldWasNullException

java.lang.Object

java.lang.Throwable

graphql.execution.NonNullableFieldWasNullException

All Implemented Interfaces:

Serializable

public class NonNullableFieldWasNullException
extends RuntimeException

See (https://spec.graphql.org/October2021/#sec-Errors-and-Non-Nullability), but if a non nullable field actually resolves to a null value and the parent type is nullable then the parent must in fact become null so we use exceptions to indicate this special case
