This is a build problem.

I have following issue:

I'm attempting to build a new react-native project. it is building and running flawlessly on Android locally. I am attempting to build it now on AppCenter and getting the following build failure:

2020-08-27T20:12:34.5372370Z error: No such file or directory (os error 2)

I have a buildType for the 'develop' release as follows:

buildTypes {
  develop {
            signingConfig signingConfigs.debug
            matchingFallbacks = ['release']
        }
}

Steps to reproduce:

• Add project to AppCenter as Android
• Choose build configuration
• Click Build Now

Actual result:
Build crashes.

Expected result:
Build doesn't crash.

I solved this on my own. Turns out you should really name your buildTypes with 'release' in them if you want react to bundle them for you! Here's the offending line from react.gradle:

enabled config."bundleIn${targetName}" != null
                ? config."bundleIn${targetName}"
                : config."bundleIn${variant.buildType.name.capitalize()}" != null
                    ? config."bundleIn${variant.buildType.name.capitalize()}"
                    : targetName.toLowerCase().contains("release")
