[Bug]: Unable to create new entity and leave ID generation up to the DB, when using UNIQUEIDENTIFIER DEFAULT NEWID()

[pingu2k4]

What happened?

Hey.
I have a table in a minimal repro, which you can create with the following:

CREATE TABLE [dbo].[NewTable](
	[id] UNIQUEIDENTIFIER NOT NULL DEFAULT NEWID(),
	[test] INT NOT NULL,
 CONSTRAINT [PK_NewTable] PRIMARY KEY ([id])
)

Go ahead and dab add this entity into your config.

The schema that DAB will be using has a CreateNewTableInput where the id field is nullable, which is accurate as the DB can handle generating the id for us.

However, if we run the mutation by passing the item in as a variable, then it fails with an internal server error.

Example mutation:

mutation CreateNewTable($item: CreateNewTableInput!) {
    createNewTable(item: $item) {
        id
    }
}

variables:

{
    "item": {
        "test": 9001
    }
}

The response I get back from DAB is the following:

{
    "errors": [
        {
            "message": "UUID cannot parse the given literal of type `StringValueNode`.",
            "path": [
                "item",
                "id"
            ],
            "extensions": {
                "field": "CreateNewTableInput.id",
                "fieldType": "UUID"
            }
        }
    ]
}
