Hi everyone! I received a crash when using my Android application.

Fatal Exception: java.lang.IllegalStateException: A migration from 2 to 1 was required but not found. Please provide the necessary Migration path via RoomDatabase.Builder.addMigration(Migration ...) or allow for destructive migrations via one of the RoomDatabase.Builder.fallbackToDestructiveMigration* methods.

I used "@notifee/react-native": "^1.7.0" for display notification.

Hey there what version of notifee are you using?

[helenaford]

I can see you have ^1.7.0 but there should be an exact version it's resolved to, either via package.lock or you can inspect the node module itself.

[MitinDmytro]

In my package-lock.json I see:

    "@notifee/react-native": {
      "version": "1.7.0",
      "resolved": "https://registry.npmjs.org/@notifee/react-native/-/react-native-1.7.0.tgz",
      "integrity": "sha512-oUuNXAkG9s42aVjMwzQxJfa6Qk1G1klFcHvTm76WiThwALlfIY7PVhgVlGHR7IPkl1aQVaitCIxO6cJT+SVEcw=="
    },

[helenaford]

Thanks. Were you using a different notifee version before this? 1.9.0+? I'm wondering if it's because you were using a newer version and then going back to an old one. I will mark this as a bug as we should take care of downgrades (a hunch this is what this could be)

[Suraj3505]

Hi, I am facing the same issue. I have the 1.7.0 version. Any solutions?

[mikehardy]

Always start by making sure you are on the current stable version of everything, in general, if at all possible. This should resolve with current versions

[helenaford]

I'm closing this as there's no solution to fix this - any solution we push will require your users to update the app, which isn't going to stop the error.

If you are facing this issue, please update the library to the latest version.
