Incorrect response returns for GraphQL Scalar type arrays

[DimuthuMadushan]

Description:
Consider the following service:

service /graphql on new graphql:Listener(9090) {
    isolated resource function get idsWithErrors() returns (int|error)[] {
       return [0, 1, 2, error("Not Found!")]
    }
}

This can be queried as follow:

{
    idsWithErrors
}

The response should be:

{
    errors: [
        {
            message: "Not Found!",
            locations: [
                {
                    line: 1,
                    column: 3
                }
            ],
            path: ["idsWithErrors", 3]
       }
    ],
    data: null
}

but currently, it returns the following:

{
    errors: [
        {
            message: "Not Found!",
            locations: [
                {
                    line: 1,
                    column: 3
                }
            ],
            path: ["idsWithErrors", 3]
       }
    ],
    data: [0, 1, 2, null]
}
