Since the big update a couple of moths ago, all scripts that were supposed to run on ALL agents (aka empty label expression) don't run anymore.
I am not sure what expression I am supposed to add to run scripts on all agents, since neither

'*'

nor

'.*'

work. I also don't want to add a label to all agents just for the sake of this plugin and imho it also doesn't make sense to try and find a (set of) label(s) to get this to work on all agents – which will break if new agents are added without that/those label(s)!
