How can i provide a a value for an argument in GraphQL?

I'm very new to GraphQL, and i'm trying to perform some example queries to this graph. In particular i'm trying the User schema.

According to that documentation, the schema is the following:

id: ID!
liquidityPositions: [LiquidityPosition!]
usdSwapped: BigDecimal!

And here is query i tried:

{
  user (where: {id: "0x7c9C48b7cBEbBDA3268435F20c81f15A538C566C"}) {
    id
    liquidityPositions
    usdSwapped
  }
}

This query fails, i keep getting the following response:

{
  "errors": [
    {
      "locations": [
        {
          "line": 0,
          "column": 0
        }
      ],
      "message": "No value provided for required argument: `id`"
    }
  ]
}

How can i provide the id field and where am i supposed to provide it? Thanks in advance!

You've got a couple of problems with that query. First, to get a user by id, remove the "where" and curly braces from your query. Secondly, the liquityPositions field needs a selection of subfields. Like so:

{
  user (id: "0x7c9C48b7cBEbBDA3268435F20c81f15A538C566C") {
    id
    liquidityPositions {
      id
    }
    usdSwapped
  }
}

That website you linked to will show you errors with your query so you can interactively learn more about what is supported.

I would also suggest running through the introduction to GraphQL here: https://graphql.org/learn/ to get a handle on how things are done.
