AttributeError: 'NestedSerializer' object has no attribute 'is_replaceable'

[sommelon]

I'm getting the above error when I try to create nested objects.

My serializers:

class ContactInfoSerializer(DynamicFieldsMixin, NestedModelSerializer):
    phones = NestedField(PhoneSerializer, many=True, required=False, allow_null=True)
    emails = NestedField(EmailSerializer, many=True, required=False, allow_null=True)

class PhoneSerializer(DynamicFieldsMixin, NestedModelSerializer):
    phone_type = NestedField(PhoneTypeSerializer)
    class Meta:
        model = Phone
        fields = '__all__'

class PhoneTypeSerializer(DynamicFieldsMixin, serializers.ModelSerializer):
    class Meta:
        model = PhoneType
        fields = '__all__'

This is the request:

{
   "contact_info":{
      "phones":{
         "create":[
            {
               "phone":"21412214124",
               "phone_type":{
                  "name":"Mobile"
               }
            }
         ]
      },
      "emails":{
         "create":[
            {
               "email":"sda@fe.cs"
            }
         ]
      }
   },
   "name":"string211111",
   "opening_date":"2021-01-21",
   "description":"string",
   "is_active":true
}

It fails when it reaches the phone_type field. Is it because I'm trying to create the PhoneType object in the create operation which is supposed to create Phone?
