Hi all,

I create node. And it has validate function for its field.

Validation has using value from 'TypedInput Select box'. They names 'node-input-action' and 'node-input-datetimeMode'. But the problem is from 'node-input-datetimeMode'.

Please see below

```auto
datetimeInitialDate: {
    value: "",
    validate: function (v) {
        if ($("#node-input-action").typedInput('value') === ACTION_DATETIMEPICKER) {
            if ($("#node-input-datetimeMode").typedInput('value') === DATETIME_MODE_DATETIME || $("#node-input-datetimeMode").typedInput('value') === DATETIME_MODE_DATE) {
                if (!v.match(/^\s*$/)) {
                    const result = isValidDate(v);
                    return result;
                } else {
                    return true;
                }
            } else {
                return true;
            }
        } else {
            return true;
        }
    }
}

```

After I run flow on browser, the client error is occured.

```auto
Validation error: node-line-bot-quick-reply-item 3f71c1a2ce19ff2a property: datetimeInitialDate value: Error: cannot call methods on typedInput prior to initialization; attempted to call method 'value'

    at HTMLInputElement.<anonymous> (red.min.js?v=2.2.2:18:375995)

```

**So how does to fix node validati error, when it get value from TyponedInput Select box?** 🤔

Moreover, I guest when I remove only code for reading 'node-input-datetimeMode' value, reading 'node-input-action' value is not error. 🤔
