Prometheus exporter problem with SecureRandom (multisite?)


(Jay Pfaffman) #1

Hey, @sam. I just tried to bootstrap a multisite instance and got this error:

Removing Prometheus plugin solved the problem.

(This should be a new topic in #bug and not a reply to Prometheus exporter plugin for Discourse, right?)

That’s not a multisite issue, that’s because that instance is not running Ruby 2.4 or higher.

Doh!

git pull
./launcher bootstrap multi

Thanks, @RGJ!
