Hello, I am following the documentation but still can't add a custom error to the validations errors !!

My code:

` class CustomEmailField(serializers.EmailField): default_error_messages = { 'unknown_email_domain': 'Email addresses ending with @example.com are not allowed.' }

def __init__(self, **kwargs):
    super().__init__(**kwargs)
    self.validators.append(self.validate_email_domain)

def validate_email_domain(self, value):
    if value.lower().endswith('@example.com'):
        self.fail('unknown_email_domain')
    return value

class EventSerializer(serializers.ModelSerializer): email = CustomEmailField()

class Meta:
    model = Event
    fields = ['id', 'name', 'email', 'start_date', 'end_date']

class EventViewSet(viewsets.ModelViewSet): queryset = Event.objects.all() serializer_class = CustomSerializer

`

Swagger 400 errors:

{ "errors": [ { "attr": "non_field_errors", "code": "invalid", "detail": "string" }, { "attr": "name", "code": "blank", "detail": "string" }, { "attr": "email", "code": "blank", "detail": "string" }, { "attr": "start_date", "code": "datetime", "detail": "string" }, { "attr": "end_date", "code": "datetime", "detail": "string" } ] }

can you make sure to check the API schema to see all possible errors? what you added under "Swagger 400 errors" seems to be from the example generated by swagger ui, rather than the API schema generated by drf-spectacular (you can check the API schema as shown in the screenshot). Otherwise, can you provide the json/yaml of the API schema generated for the code you provided?

aha, I thought it could be displayed in examples thanks for your help !!
