Nullable Record Fields Identified as NON_NULL Fields in GraphQL

[ThisaruGuruge]

Description:
When a record type has a nullable field, the GraphQL schema generated is considering them as NON_NULL fields.

Example:

type Person record {
    string? name;
};

The above record is mapped to the following type:

type Person {
    name: String!
}

But this should be;

type Person {
    name: String
}
