I suppose you use @ionic/storage and you miss this.storage.create(); call.

From documentation:

Next, inject Storage into a component. Note: this approach is meant for usage in a single component (such as AppComponent). In this case, create() should only be called once. For use in multiple components, we recommend creating a service (see next example).

import { Component } from '@angular/core';
import { Storage } from '@ionic/storage-angular';

@Component({
    selector: 'app-root',
    templateUrl: 'app.component.html'
})
export class AppComponent {
    constructor(private storage: Storage) {}

    async ngOnInit() {
      // If using a custom driver:
      // await this.storage.defineDriver(MyCustomDriver)
      await this.storage.create();
    }
}

For React, Vue, Vanilla JavaScript logic the similar (documentation):

import { Storage } from '@ionic/storage';

const store = new Storage();
await store.create();
