Constant Loading is already suppressed (RuntimeError)

[omarabdelaziz22]

Describe the bug
When running my application after updating from 2.2.1 to 3.3.0 it throws Constant Loading is already suppressed (RuntimeError). It happens in development, production and test environments.

Reproduction steps
update to 3.3.0

Expected behavior
No errors

Additional context

• rails version: 7.1.0
• rails_admin version: 3.3.0
• rails_admin npm package version: 10.8.3
• full stack trace (if there's an exception)

It worked only when I changed this line raise 'Constant Loading is already suppressed' if @original_const_missing inside the file /rails_admin-3.3.0/lib/rails_admin/config/const_load_suppressor.rb
to return if @original_const_missing

[mshibuya]

Please provide full stack trace, and the content of config/initializers/rails_admin.rb.

I had the same error message, and found out my initializer was the problem.

Try to put p *caller at the start of the suppressor method in /rails_admin-3.3.0/lib/rails_admin/config/const_load_suppressor.rb. This will show you from where the call is being made, and probably point you to where there is a problem.

@mshibuya @petrachi Actually it's working normally now and the solution was to move all custom actions that were in a separate files into the config.actions block inside the main rails_admin.rb initializer.
Separate files were working fine but before upgrading the rails admin version maybe this needs to be included in the Release notes
