Use variable in googleSheet Update

[amaillet2024]

Hello,
I need to update 2 selected cell in a google sheet. I don't want to create a table for 2 fixed data in my workflow.
(I change the edited line in a loop and need to update row by row)

When I use fixed data it works fine.
For example : [["Publié","01/04/2424"]]

but if I change to [["Publié",{{variable@today}}]]
it doesn't work, I have the error : [body] "values" must be an array On the Google Sheets block

I tried to set a var to an array, for exemple : myVar => [["Publié",{{variable@today}}]] and use {{variables@myVar}} in the googlesheet block
also by using JS block...

But it doesn't help

can someone help me ?

regards,
Annabelle
