Argument of type 'typeof Store' is not assignable to parameter of type 'Store<AppState>'

I'm trying to extend an angular service that uses ngrx and I'm getting this type error

Argument of type 'typeof Store' is not assignable to parameter of type 'Store<AppState>'

Here is my parent class:

import { Store } from '@ngrx/store';
import { AppState } from '../store/file-uploader.state';
import { AbstractStorage } from '@storage';

export class FileUploaderService {
    constructor(
        private store: Store<AppState>,
        private storage: AbstractStorage,
    ) { }
}

And my child class:

import { Store } from '@ngrx/store';
import { AppState } from '../store/file-uploader.state';
import { AbstractStorage } from '@storage';

export class DataSourceService extends FileUploaderService implements AbstractFileUploader  {
    constructor() {
        super(Store, AbstractStorage)
    }
}

I have to pass these 2 arguments to super. I've tried passing Store<AppState>, but it says it's using Appstate as a value, not a type. So I don't know how to type this arg. Does anyone know how to declare this super correctly?

You should be passing the instances to super and not type. You can try below code and see if it helps:

    export class DataSourceService extends FileUploaderService implements AbstractFileUploader  {
      constructor(private store: Store<AppState>, private storage: AbstractStorage) {
          super(store, storage);
      }
    }
