The module was not added in the upgrade constants.

It is not wired correctly without it.

Check here:

You need to bump the timeout on e2e tests to 30-35 minutes.

Upgrade test is expected to fail since v16 upgrade handlers don't work correctly - that's for another PR.

You need to bump the timeout on e2e tests to 30-35 minutes.

It's already 45m, i.e.,

  test-e2e:
    runs-on: ubuntu-latest
    timeout-minutes: 45

LGTM!
