An issue has occurred with the NullInjector, specifically regarding the AppModule and Storage in Ionic 4

When attempting to launch my Ionic app using npm start, an error message appears stating "NullInjectorError: No provider for Storage!".

I have already included Storage in the app.module.ts file as shown below:

imports: \[
BrowserModule,
IonicModule.forRoot(),
AppRoutingModule,
IonicStorageModule.forRoot(),
HttpClientModule,
ModalPayConfirmationPageModule,
ModalAlergenPageModule
\],

The version of Ionic I am using is Ionic 4. Any assistance on resolving this issue would be greatly appreciated.

I have tried various solutions such as reinstalling Storage and Ionic, as well as removing and adding IonicStorageModule.forRoot() in the app.module.ts file.

Answer №1

To ensure Storage functionality in your app, include it in your app.module.ts file

imports: [...],
providers: [Storage]

Alternatively, you have the option to place your service at the root level.

Injectable({ providIn: 'root' })
