Android crashing after upgrade to Expo 48

  1. SDK Version: 48
  2. Platforms(Android/iOS/web/all): Android

Hey guys, after upgrading Expo to version 48 I can’t start the Android app, the iOS is working fine. This is the error message that I get:

java_vm_ext.cc:577] JNI DETECTED ERROR IN APPLICATION: JNI GetObjectRefType called with pending exception expo.modules.kotlin.exception.MissingTypeConverter: Cannot find type converter for 'expo.modules.kotlin.Promise'.

Does anyone know how to resolve this?

Thanks!

Sounds like there’s a version mismatch somewhere. The surrounding lines in the logs may indicate which package the error is originating from. Also, check the output of npx expo-doctor to see if it sees any packages using unexpected expo-modules versions.
