Column 'file_date' cannot be null [Solved in jD4.0.20]

[serge]

hello

I have migrated my site to j4
it was hard but I can see my files on front and DL them
but in back end, when I want to save one, I have this message : L'enregistrement a échoué avec l'erreur suivante : Column 'file_date' cannot be null
If i do "save and new" I have another error : Field 'url_download' doesn't have a default value
I do not know what to do
thanks

I updated to last version and it works
