Relationship exists in Resource object error

[designvoid]

The response from the API has attributes that are the same name as an included resource.

Detailed description

The response from the API has attributes that are the same name as an included resource:

            "type": "property",
            "id": "fc7ecf3f-0f3a-4e8c-920e-7e1db01cac8b",
            "attributes": {
                "sales": true,

Where sales can also be an optional include.

This causes an error stating:

Relationship "xxx" cannot be set because it already exists in Resource object.

My question is if this is a known issue, something that can be wroked around or just going to be a problem for me using this package?

Unfortunately this is by design. We follow the specification and that disallows attributes and relationships with the same name.

Fields for a resource object MUST share a common namespace with each other and with type and id. In other words, a resource can not have an attribute and relationship with the same name, nor can it have an attribute or relationship named type or id.
