Taking time value and returning a value that will pass a moment().isValid() check

I am running some checks on a value that is passed into a timePicker on my react-native app, and I want to take a time value like 14:29, which is coming in as a string, and turn that into a value that will pass a moment(val).isValid() check.

How can I, for instance, just take today's date, but set the time to be this value of 14:29?

I tried this but it errors out:

let val = '14:29';
this._value = moment(new Date()).startOf(val);

Docs: set, startOf.

const input = '14:29';
const [hour, minute] = input.split(':');

const myMoment = moment()
  .set({ hour, minute })
  .startOf('minute');

console.log(
 { myMoment, isValid: myMoment.isValid() }
)
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.29.1/moment.min.js"></script>

Note: this will respect the browser timezone meaning different users will get different moments in time, depending on their system's currently set timezone.
To set a particular timezone you might want to use .tz(). Docs: moment timezone.
