@Nuzair46 what do you think about this one?

[Nuzair46]

@pkuczynski @vovanmozg the failing tests seems to be an issue with Rails 6.1 not loading logger properly.
I was able to fix it by doing this
This can be identified by rescue in the runner code. And I saw logger error.
Before:

`#{Rails.root.join("bin", "rails")} runner 'print "\#{Settings.default}|\#{Settings.custom}"'`

After:

`RUBYOPT="-r logger" #{Rails.root.join("bin", "rails")} runner 'print "\#{Settings.default}|\#{Settings.custom}"'`

This makes ruby to load the logger before anything runs.

@vovanmozg Are you able to contribute to this? Or I can help with implementing the rest.

That would be awesome if you could take it over — I’m short on time right now. Really appreciate it!
