getDMMF not returning @relation fields argument

[gfpacheco]

I have a schema like this:

model Post {
  id       Int    @default(autoincrement()) @id
  author   User   @relation(fields: [authorId], references: [id])
  authorId Int
}

And I'm using getDMMF to get the schema information so I can generate code for it.

But it doesn't tell me the fields argument for the @relation directive. This is all I get for the author field:

    {
      "name": "author",
      "kind": "object",
      "dbNames": [],
      "isList": false,
      "isRequired": true,
      "isUnique": false,
      "isId": false,
      "type": "User",
      "relationName": "PostToUser",
      "relationToFields": [
        "id"
      ],
      "relationOnDelete": "NONE",
      "isGenerated": false,
      "isUpdatedAt": false
    },

Is there any way to get that information?

Thanks for asking @gfpacheco !
As the fields argument of the @relation directive is fairly new, we didn't add it to the DMMF yet. I will ping you here, once we have added it.
