LGTM. Thanks for fixing!

[damirka]

@acoglio these three checks related to APM won't pass because the PR was created by a non-team developer, and the CIs don't have permissions to access CI secrets.

[acoglio]

@damirka If someone from our team can double-check that those failing CI tests work for him, I think we are fine.

[rapiz1]

Should I retarget it onto staging?

[gluax]

@rapiz1 that would be helpful!
