Bug#1126068: ubuntu-sponsorships is returning no results (for "recent" uploads?)

Package: qa.debian.org
User: [email protected]
Usertags: udd

It seems UDD ubuntu-sponsoring  is failing to return (recent?) uploads, 
example URL from 
https://discourse.ubuntu.com/t/application-ubuntu-contributing-developer-nadzeya-hutsko

https://udd.debian.org/cgi-bin/ubuntu-sponsorships.cgi?render=html&sponsor=Nick+Rosbrook&sponsor_search=name&sponsoree=Nadzeya+Hutsko&sponsoree_search=name

is returning an empty list

where it should be listing entries like those
https://launchpad.net/ubuntu/+source/vim/2:9.1.1882-1ubuntu1
https://launchpad.net/ubuntu/+source/rust-rav1e/0.8.1-6ubuntu1

Checking my firefox history I've an URL example which I think worked 
some months ago and is returning no result now
https://udd.debian.org/cgi-bin/ubuntu-sponsorships.cgi?render=html&sponsor=Sebastien+Bacher&sponsor_search=name&sponsoree=Alessandro+Astone&sponsoree_search=name

Searching for packages I sponsored return a list starting in 2007 though 
so the service has still some data/is at least partially working...


Cheers,
Sébastien
