Duplicating Debug Configuration Does Not Connect to Packager on iOS

See original GitHub issue

Description

I am trying to simply switch the Run Phase for iOS that points to Debug to a new configuration, DebugQA

I have duplicated the Debug configuration to DebugQA and everything works great except when the app launches. It crashes with:

No bundle URL present.\n\nMake sure you're running a packager server or have included a .jsbundle file in your application bundle.

React Native version:

react: 16.9.0 => 16.9.0 react-native: 0.61.5 => 0.61.5

Steps To Reproduce

Provide a detailed list of steps that reproduce the issue.

Duplicate Debug Build Configuration in XCode, name it DebugQA
Modify scheme Run confiuration to point to DebugQA
cd ios && pod install && cd ..
start bundler react-native start
react-native run-ios
app builds, installs, launches
Error:

No bundle URL present.\n\nMake sure you're running a packager server or have included a .jsbundle file in your application bundle.

Expected Results

I would expect this new config to behave just like the existing Debug config and connect to metro bundler/ packager.

I have made sure the metro bundler is running and if I switch the Run configuration back to Debug it works fine. It’s almost as if the app’s new config isn’t making the GET for the bundle from the metro bundler.

Making a GET to the bundler outside of the app responds just fine.

I’ve had success building other packages using this method however never creating a new Debuggable config that tries to connect to metro bundler. Any help is greatly appreciated.
