TypeError · undefined is not a function (evaluating 'c.askAsync(e)')

After upgrading to 29.0.0, I’m getting a bunch of those errors reported by Bugsnag 😕

Any idea on how to fix?

Hi @mjgallag!

Could you please try appending the following snippet to the proguard-rules.pro file and then enabling the minification and stripping back?

-keepclassmembers class * {
  @expo.core.interfaces.ExpoProp *;
}
-keepclassmembers class * {
  @expo.core.interfaces.ExpoMethod *;
}

-keepclassmembers class * {
  @**.expo.core.interfaces.ExpoProp *;
}
-keepclassmembers class * {
  @**.expo.core.interfaces.ExpoMethod *;
}

// app/build.gradle

// ...

buildTypes {
  // ...

  release {
    minifyEnabled true
    proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    // ...
  }
}

Unfortunately disabling minification/proguard doesn’t work for us as our detached app is too big so it leads to Too many classes in --main-dex-list, main dex capacity exceeded. @sjchmiela Any other workarounds we can try or ETA on fix? Thanks!
