Invalid error message for readonly types with parseString API in jsondata module

[SasinduDilshara]

import ballerina/data.jsondata;
import ballerina/io;

type User readonly & record {|
    int id;
|};

public isolated function main() returns error? {
    string user2 = string `{"id": 4012}`;
    User r2 = check jsondata:parseString(user2);
    io:println(r2.id);
}

This gives error: unsupported type '(readonly & record {| int id; |})'.
This should be a valid usecase.
