The first idea I get is that probably proguard is renaming the field as obfuscation is on?

This is where the error seems to be coming from:

                val versionClass = Class.forName("com.facebook.react.modules.systeminfo.ReactNativeVersion")
                val versionMap: Map<String, Int> = Reflect.on(versionClass).field("VERSION").get()

To Reproduce

• I have tested this issue on the latest Detox release and it still reproduces

Steps to reproduce:

1. Setup proguard on the release app.
2. Setup detox
3. Run tests

Expected behavior App should not crash.

Issue got fixed by adding:

-keep class com.facebook.react.modules.systeminfo.ReactNativeVersion {*;} to proguard rules.
