date column editing "The specified value does not conform to the required format, "yyyy-MM-dd"

[butachan]

Hi I have some problem with my editable date column when entering editing mode.
To start with, my column is defined as :

Cell: ({ cell }) => cell.getValue<Date>()?.toLocaleDateString('en-US', {day:'numeric',month:'short',year:'numeric'})

which looks like Nov 23, 2023 .

My problem is that when this column is already filled and I enter editing mode, the date disappear, and the default date position in the datepicker is today's date and not the actual date, and I have a console warning :

The specified value does not conform to the required format, "yyyy-MM-dd

I assume these 3 behaviours are all related to the same problem.

i use row as editing mode

Do you have any idea how to get the editing mode cell to pick the correct format ?
