I’ve got a local development installation of Discourse running on my Ubuntu machine. I’ve got the main development version up and running just fine by following [the local install guide](https://meta.discourse.org/t/beginners-guide-to-install-discourse-on-ubuntu-for-development/14727). Given the new addition of ember-cli, I’ve got that running, too, proxying to the Rails app. I’m able to fully interact with the desktop version of the app.

However, when I use Chrome’s DevTools to view the mobile version, things aren’t working. I simply get a blank page with a “200 OK” response, but absolutely no content. It’s just entirely blank.

I can see via the Rails logs that it is rendering _something_, but it doesn’t seem to get proxied through Ember.

```plaintext
Started GET "/" for <redacted> at 2022-01-31 22:51:03 +0000
   Rendering layout layouts/application.html.erb
   Rendering categories/index.html.erb within layouts/application
   Rendered categories/index.html.erb within layouts/application (Duration: 2.8ms | Allocations: 925)

   Rendered layouts/_body_tag.html.erb (Duration: 0.1ms | Allocations: 21)
   Rendered layout layouts/application.html.erb (Duration: 22.6ms | Allocations: 4961)

```

ember-cli isn’t logging anything about the request.

Presumably I’ve misconfigured something and it’s throwing an error somewhere, but I just can’t seem to figure out where or how to get the error the show. Are there any additional flags or environment variables I can set to get more verbose logging around this issue? I have tried setting `DEBUG=ember-cli:*` as suggested [here](https://cli.emberjs.com/release/advanced-use/debugging/) but this didn’t log anything about the request.

Any help around this issue would be greatly appreciated! Long time user of Discourse, thanks for developing it!
