带有Api平台的GraphQL在GraphiQL中返回null

Question

I have setup api-platform without docker in a Symfony 4 skeleton and have added GraphQL support as mentioned here - https://api-platform.com/docs/core/graphql

When using GraphiQL I seem to only get null responses, I have tried a lot of different GraphQL syntax, all returning null.

Null response in GraphiQL

Ive tried:

{
  user{
    id
  }
}

-

{
  user(id: 1){
    id
  }
}

-

{
  users(id: 1){
    id
  }
}

All with no luck

I can request the api normally and I get a response.

Successful request in API tester

Also, the requests in GraphiQL seem to all be post, this might be unrelated though.

Ive been trying to fix this for a while now and haven't managed to find any help online.

Thank you

Well I found the answer for those having the same issues.

api-platform uses uuids and you have to search with this in graphql

query {
    user(id: "users/1"){
        firstName
        lastName
    }   
}
