@nkolev92 it seems like the ci is hung on this, do we need to do something ?

[nkolev92]

@Anipik the CI for people without write access doesn't run automatically.

Kicked it off.

@Anipik

There's some test failures. Can you access the following, check out the test table for partial results.

The tests that are failing are pack specific.
