Problem with filled cell "Date" type

[okokokokokokokokok (okokokokok)]

Hello. I add the last row with filled cells with this code:

“Date” type columns are declared as follows:

But there is a problem with their cells . In debugger hot.getData() method(last row in picture 1) return their values as null, but in the table they are filled.

Tell me please how can I solve this problem?

Try to add ~100ms delay for the hot.loadData() call.
