HTTP requests work in dev but not after publishing

Expo SDK
1

I’m developing an app that does a series of HTTP requests to my Heroku backend server. I’m using the xmlHttpRequest() function.

When in dev mode (exp start) and running on my iPhone, everything works correctly. When I publish the project, the xmlHttpRequest() fails.

Any help on debugging or fixing? I’m not sure how to debug after publishing - is this possible? Even a console would help me look at the failure messages.

I’m guessing it’s something to do with some configuration or possibly iOS related. Any ideas? Thanks.

You can run the project with --no-dev --minify to simulate a publish locally. If that reproduces your problem, you can add logs and try to figure out what’s going on then.
