NameError: uninitialized constant Signalman::EventsHelper

[cgratigny]

I installed the gem, ruby 2.7.4 and rails 7.0.3.1 and got this error when trying to start my rails server or running the migrations.

NameError: uninitialized constant Signalman::EventsHelper

One thing that might be unique in my setup is I am using the Apartment gem for multi-tenancy.

You got a stacktrace you can share?

Would you be able to upload a simple repository that recreates this or provide me steps to recreate it?

[ashwin47]

I also faced this. But, not able to reproduce with a new rails repo.
