On download of a chart from Helm hosted (pushed via curl) in PostgreSQL, the last downloaded remains "has not been downloaded" in the UI and "[null]" in the database.
Helm proxy seems to update fine.
I checked 3.30.1 in Orient and this does not occur. In fact, the download date seems to update on push (which I am not sure is right either frankly).
In addition, I did clear cache before repro attempt to make sure something wasn't weirdly caught in my Downloads folder.
So this seems regression, assuming the behavior isn't intentional.
