Why does FaunaDB output differ from Graphqli?

I have created a simple user.gql file

type Query {
users: [user]
userById(id:ID!):user
}

type user {
id: ID!
chat_data: String
}

My data is

 [
    {
        "id": "0815960b-9725-48d5-b326-7718c4749cf5",
        "chat_data": ""
    }
]

When I run this on my local server and use the query

{users{id}}

I see the expected output

{
"data": {
    "users": [
    {
        "id": "0815960b-9725-48d5-b326-7718c4749cf5"
    }
    ]
}
}

I have created a user collection on FaunaDB with the data

{
    "ref": Ref(Collection("user"), "324407037973758152"),
    "ts": 1645691670220000,
    "data": {
        "id": "0815960b-9725-48d5-b326-7718c4749cf5",
        "chat_data": ""
    }
}

and uploaded my user.gql, but when I run the GraphQl query

{users{id}}

I get the error

{
    "data": null,
    "errors": [
        {
        "message": "Cannot query field 'id' on type 'userPage'. (line 3, column 5):\n    id\n    ^",
        "locations": [
            {
            "line": 3,
            "column": 5
            }
        ]
        }
    ]
}

What am I doing wrong?

This is very unintuitive, but Fauna seems to be returning a paginated result. Read more about it here.

The best thing would be to GraphiQL to have a look at the schema of the Fauna GraphQL endpoint. Autocomplete should also work when you look for fields to query. The error basically says that you can't query the id directly. Try this:

{ users { data { id } } }
