The ballerina project crashes without giving a proper error message for associated entities containing defaultable fields

Description: When tried to generate the clients for the following model, the project crashes without giving the expected error output.

import ballerina/persist as _;

public type Phone record {|
    readonly string id;
    boolean sms = true;
|};

public type Person record {|
    readonly string id;
    Phone[] phones;
|};

The crash log looks like following:
