That's because it has no meaning there -- there's no row to take the number from. Try $id instead.
Thanks Nyall for your fast answer. $id Is not a good option because working with geopackage fid is authomatic and if you delete any row, the number will not be consecutive (let me try to show you and example. I need to automatise a consecutive id in a point layer. I need as shown in @row_number: 1 2 3 ):
First you create 5 points: fid will be: 1 2 3 4 5 and @row_number will be: 1 2 3 4 5
Then Delete 3 and 4. fid will remain: 1 2 5 but @row__number will be: 1 2 3
