Error using add list item from sharepoint activity (Type problem on empty values)

Hey there,

I’m having trouble adding elements to a sharepoint list using the add list item activity from the sharepoint one.

The data I import are in an excel file, this works great except for the Date column because some rows are empty and I get the following error :

Basically the empty values are considered as string on Sharepoint but the column type is Date on sharepoint (and must be date).

Thanks in advance for your help !
