createMigrate not triggered

[JohnBerd]

Hello, I am using redux-persist in a React Native project. Everything is working fine but impossible to create a migration. The debugMode is at true but nothing is logged in my console, version is well incremented for the action persist/PERSIST, but then the store is simply rehydrated as it used to be without any change.

Here is my code:

const storage = createSecureStorage()

export const migrations = {
  20: (state) => ({ ...state, user: { ...state.user, hello: true } }),
}

const persistConfig = {
  key: 'storage',
  version: 20,
  storage,
  migrations: createMigrate(migrations, { debug: true }),
  whitelist: ['user'],
  blacklist: [],
}

export const rootReducer = combineReducers({
  [api.reducerPath]: api.reducer,
  user: userReducer,
})

const persistedReducer = persistReducer(persistConfig, rootReducer)

export const store = configureStore({
  reducer: persistedReducer,
  middleware: (getDefaultMiddleware) =>
    getDefaultMiddleware({
      serializableCheck: false,
    }).concat(api.middleware),
})

export const persistor = persistStore(store)

Any idea?

I am experiencing the same issue, I tried to restore redux packages to versions where I remember the migration used to work but it did not fix it. The old versions I tested: "react-redux": "7.2.2", "redux": "4.0.5", "redux-persist": "^6.0.0", "redux-thunk": "2.3.0" Not sure if its might be related to other packages or not. I am using react 17.0.2 & react-native 0.67.4 Also when I migrate a version I can see in the log: LOG redux-persist: migrationKeys [9] LOG redux-persist: running migration for versionKey 9 But the issue is that the returned state I set in the function is not being returned instead its rehydrated state as before the migration.

I think createMigrate is broken. When using the Promise.resolve method mentioned https://github.com/rt2zz/redux-persist/blob/master/docs/migrations.md it works
