Wendy, tbh your solution works BUT not in the way I expect 😄
So main issue that I push some data into Custom CRM Card, and it contains some dt fields. 2 of them always have some dt values but the issue with the 3rd one which in the most cases won't have a value, and before it showed Invalid property in the card - which looked weird and from end user perspective as something has been broked.
After I start to push blanks '' to that field it started to look as showed bellow:

Instead of sending NULL, try passing a blank empty string "". While this won't show dt: null, it'll display the entire card just fine and shows the following
