GraphQL Service Crashes when Input Object Type Variable Value Includes an Additional Field

[DimuthuMadushan]

Description

GraphQL service crashes when the input object type variable value includes an additional field.

Steps to Reproduce

Consider the below service:

import ballerina/graphql;

type NewProfile record {|
    string name;
    int age;
|};

type Profile readonly & record {|
    *NewProfile;
    int id;
|};

table<Profile> key(id) profiles = table [];

service /graphql on new graphql:Listener(9090) {
    remote function addProfile(NewProfile newProfile) returns Profile {
        Profile profile = {id: profiles.nextKey(), ...newProfile};
        profiles.add(profile);
        return profile;
    }

    resource function get profiles() returns table<Profile> {
        return profiles;
    }
}

Service is crashing for the following GraphQL query.

mutation($profile: NewProfile!){
  addProfile(newProfile:$profile) {
    id
    name
    age
  }
}

variable:

{
  "profile": {
    "name": "gql",
    "age": 4,
    "address": {}
  }
}

output:

error: {ballerina/lang.map}KeyNotFound {"message":"invalid field access: field 'address' not found in record type 'input_obj:NewProfile'"}
