5.2.0.beta2 doesnt load in dev mode.

[XenorPLxx]

Steps to reproduce

I've just upgraged project to 5.2.0.beta2 and it doesn't work in dev mode.

I sincerely don't have a clue where to start my investigation, but I think it's connected somehow to assets - it works fine in production configuration with precompiled assets.

I tried setting config.assets.debug = false for development, but it didn't work either.

My sidekiq jobs work correctly in dev mode.

Expected behavior

Something should load.

Actual behavior

Application explodes with stack overflow.

System configuration

Rails version: 5.2.0.beta2 / master@4c4d092

Ruby version: 4.2.1

I've tracked down problem to meta_request gem and posted an issue in gem's repo.
dejan/rails_panel#137

[kaspth]

Great! I'll close this since the issue seems to be with the gem and not Rails 😊
