Local Storage, Cannot read property 'platformId' of undefined

Question

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",

Yes 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

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.
