null date handling?

[squarewave24]

i looked at all the examples and googled for 30 minutes but can't seem to make this work if the date is optional

"moment": "^2.24.0",
"react-moment": "^0.8.4",

doing this with optional endDate field:

<Moment format="MMM DD YYYY HH:MM">
    {`${r.endDate}`}
</Moment>

error:

moment.js:299 Deprecation warning: value provided is not in a recognized RFC2822 or ISO format. moment construction falls back to js Date(), which is not reliable across all browsers and versions. Non RFC2822/ISO date formats are discouraged and will be removed in an upcoming major release. Please refer to http://momentjs.com/guides/#/warnings/js-date/ for more info.

and invalid date is written in place

i'd like to ignore null or invalid date..

Also, <Moment fromNow>{ undefined }</Moment> is rendered as a few seconds ago 😖

AFAIK react allows conditional rendering (docs):

<div>{r.endDate && <Moment format="MMM DD YYYY HH:MM">
    {`${r.endDate}`}
</Moment>}</div>

Otherwise it is hard to tell which behavior ought to happen:
a) throw when invalid argument
b) render with implied new Date
c) render nothing
