Local Storage, Cannot read property 'platformId' of undefined

Issue

Hi I am developing an ionic-angular pwa and recently I decided to use local storage to store authentication info. I followed the steps according to Ionic Storage

But in the end I get the following error:

AppComponent_Host.ngfactory.js? [sm]:1 ERROR TypeError: Cannot read property 'platformId' of undefined
at provideStorage (ionic-storage-angular.js:49)
at _callFactory (core.js:23707)
at _createProviderInstance (core.js:23663)

The only way I could solve the error is to add Storage to the Providers list in app.module.ts; But according to recent release I should not. I would be thankful if you can tell my what is wrong.

My packages versions are:

"@ionic/angular": "^5.5.2",

"@ionic/storage": "^2.3.1",

"@ionic/storage-angular": "^3.0.6",

Solution

I was able to solve this error by adding Storage to the Providers list in app.module.ts. However you need to import the Storage package from @ionic/storage-angular rather than @ionic/storage. I know that the recent release currently says not to do this, but i was unable to run my application with this entry.

Try this in your app.module.ts

import { IonicStorageModule,Storage } from '@ionic/storage-angular';

@NgModule({
  imports: [
    IonicStorageModule.forRoot()
  ],
  providers: [
    Storage
  ]
})
export class AppModule { }

And this is the only way it worked for me.
