Description

I have a simple demo for rendering a 3d object in an AR scene that i’ve made an issue about here earlier. When I was working at the office on this, I was able to use the testbed app just fine. I’m at home now, with my phone and macbook pro on the same wifi network. I’ve ensured the ngrok URL i’m entering has no typos. I know this demo works because the code has been unchanged since it was last running it at the office. Now that I’m home I try to run npm run start and enter my ngrok URL into the testbed app on my iphone X and constantly get this Failed to load bundle error and I cannot navigate around this. I tried sideloading it on my iphone with xcode but get a compilation error about a missing config.h file.

Screenshot of error:

Reproducible Demo

This doesn’t appear to happen consistently, since all of today it was fine but now with unchanged code I cannot get the testbed app up and running. This would be my personal repo to refer to.
