I don't know what's wrong with the docs tests:

 E: Failed to fetch https://packages.microsoft.com/ubuntu/22.04/prod/dists/jammy/InRelease  Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?)
E: The repository 'https://packages.microsoft.com/ubuntu/22.04/prod jammy InRelease' is no longer signed.

Looks like some issue with Microsoft or GitHub.

LGTM

(It is not possible to enter null as a filter value in GET, but this should be targeted by #757
)

Also merging this on red docs tests since

• this PR doesn't touch the docs
• it seems to be infrastructure related
