The simplest version of the error

import ballerina/io;
import ballerina/data.jsondata;
public type User readonly & record {|
    int id;
|};

public function main() returns jsondata:Error? {
    json user2 = {id: 4012};
    User r2 = check jsondata:parseAsType(user2);
    io:println(r2);
}

type DDPerson record {|
    readonly int id;
|};

DDPerson rs = check jsondata:parseAsType({id: 10});
