Inherits:
Error

Defined in:
lib/graphql/schema/enum.rb

Overview

This is raised when either:

  • A resolver returns a value which doesn’t match any of the enum’s configured values;
  • Or, the resolver returns a value which matches a value, but that value’s authorized? check returns false.

In either case, the field should be modified so that the invalid value isn’t returned.

GraphQL::Schema::Enum subclasses get their own subclass of this error, so that bug trackers can better show where they came from.
