Reference fields are disabled when using UI policies

[Yuki21]

Hello.
Implemented a script to deactivate a screen field in case of certain status in UI policy.

I have a field in my script that I don't want to deactivate, but I'm using exception handling,
but the reference field button doesn't work.
What is the cause?

＜UI policy＞

＜UI policy Script＞

function onCondition() {
//必要に応じて条件を挿入
        var notReadOnly = ["u_choice_3","u_shounin_user_id","u_shounin_pw","u_sekininsha_user_id","u_sekininsha_pw","request"];
        var fields = g_form.getEditableFields();  //フォームの編集可能フィールを取得
        for (var x = 0; x < fields.length; x++) {
            if(notReadOnly.indexOf(fields[x]) == -1){
                g_form.setMandatory(fields[x], false);  //必須を無効にする
                g_form.setReadOnly(fields[x], true);    //読取り専用にする
            }
        }
	g_form.setReadOnly("variables."+ req_category_1, true);
	g_form.setReadOnly("variables."+ req_category_2, true);
	g_form.setReadOnly("variables."+ req_category_3, true);
	g_form.setReadOnly("variables."+ req_category_4, true);
	g_form.setReadOnly("variables."+ req_category_5, true);
	g_form.setReadOnly("variables."+ req_device_1, true);
	g_form.setReadOnly("variables."+ req_device_2, true);
	}

It is under investigation, but after commenting out the following processing in the script, the reference button can now be pressed.
However, what I'm making ReadOnly below is a different field than the reference field.
The requirement to make the fields of variables. ReadOnly is necessary.
I don't know why it affects me...

    g_form.setReadOnly("variables."+ req_category_1, true);
    g_form.setReadOnly("variables."+ req_category_2, true);
    g_form.setReadOnly("variables."+ req_category_3, true);
    g_form.setReadOnly("variables."+ req_category_4, true);
    g_form.setReadOnly("variables."+ req_category_5, true);
    g_form.setReadOnly("variables."+ req_device_1, true);
    g_form.setReadOnly("variables."+ req_device_2, true);

Hi,

What are "req_category_1", "req_category_2" etc. ? Are these catalog variable names ?

If so, then please change

    g_form.setReadOnly("variables."+ req_category_1, true);

to

    g_form.setReadOnly("variables.req_category_1", true);

and try.

Thanks,

Arav

Thank you very much for your advice.
I solved it with a client script.
