[Bug] upmost __typename in mutation finds no resolver

I have the same issue but with query now.
OperationException(linkException: null, graphqlErrors: [GraphQLError(message: Operations not allowed – [__typename], locations: null, path: null, extensions: null)])

I use graphql 5.1.1 library for flutter.

Corresponding issue is described here.

https://github.com/zino-hofmann/graphql-flutter/issues/784#issuecomment-749005581

and I recreated it in the explorer:


query getUserProfile($username: String!) {
  __typename  
  getUser(username: $username) {
        __typename
        username
    }
}

returns

{
  "data": null,
  "errors": [
    {
      "message": "Operations not allowed -- [__typename]"
    }
  ]
}

Mutation does not work either so maybe it was not merged into the cloud.

mutation MyMutation2($name: String = "", $country: String = "") {
  __typename
  addCity(input: {name: $name, country: {name: $country}}) {
    __typename
    city {
      id
      name
    }
  }
}


{
  "data": null,
  "errors": [
    {
      "message": "Operations not allowed -- [__typename]"
    }
  ]
}
type Country{
  id: ID!
  name: String
  region: [Region!] @hasInverse(field: country)
  cities: [City!] @hasInverse(field: country)
  
} 
    
type Region{
  id: ID!
  name: String
  country: Country @hasInverse(field: region)
  guide: [Guide]
  
}

type City{
  id: ID!
  name:String
  country: Country! @hasInverse(field:cities)
  location: Point
  
}
