What could be causing the error in the console when I try to declare datetime in Ionic?

I am just starting out with Ionic and Angular, but I seem to have hit a roadblock. The compiler is throwing an error that says:

node_modules_ionic_core_dist_esm_ion-app_8_entry_js.js:2 TypeError: Cannot destructure property 'month' of '(0 , _data_cb72448c_js__WEBPACK_IMPORTED_MODULE_9__.P)(...)' as it is undefined.
    at Datetime.processValue (ion-datetime_3.entry.js:702:15)
    at Datetime.componentWillLoad (ion-datetime_3.entry.js:1082:10)
    at safeCall (index-8e692445.js:1458:36)
    at dispatchHooks (index-8e692445.js:1315:23)
    at Array.dispatch (index-8e692445.js:1299:28)
    at consume (index-8e692445.js:2242:21)
    at flush (index-8e692445.js:2257:9) undefined

Within my HTML file, I have included an "ion-datetime" component.

<ion-item>
    <ion-datetime [(ngModel)]="dateTime">
    </ion-datetime>
  </ion-item>

In my TypeScript file, I initialize dateTime as follows:

dateTime:Date=new Date();

I have also attempted to assign specific values to dateTime, but haven't had any success.

dateTime:Date=new Date('1990-12-20');

I am completely stumped by this issue and have been struggling for hours. Any assistance would be greatly appreciated. Thank you.

When using ion-datetime, it utilizes the ISO 8601 datetime format for its value. Instead of relying on JavaScript's Date object, the value is simply stored as a string. To solve any issues you may encounter, make sure to declare the dateTime value as a string. I suggest utilizing moment.js for easier formatting of current time:

<ion-datetime display-format="YYYY-MM-DD" [(ngModel)]="dateTime"></ion-datetime>
dateTime:string=moment().format('YYYY-MM-DD');
