GraphQL query error message: argument is required, but it was not provided

I'm new to grapghql and my query fails.

I'm using

{
  product {
    id
  }
}

"message": "Field "product" argument "id" of type "String!" is required, but it was not provided."

Thank you for your help

It looks like you're making a query for a Product object.

GraphQL queries may require arguments, you can read more about that here.

The error message is telling you that field product requires argument id of type String!.

That means you must know the id of a Product and then can query more fields.

Let's assume there is a product with id: "abc42". A query then might look like:

{
  product(id: "abc42") {
    name
  }
}

In this query the id is hardcoded. There are ways to pass the id dynamically, but that depends on your code and the libraries you are using.
