sqlite.create returning null in Angular

Question

Below are my imports in my database.service.ts.

import { Platform } from '@ionic/angular';
import { Injectable } from '@angular/core';
import { SQLitePorter } from '@ionic-native/sqlite-porter/ngx';
import { HttpClient } from '@angular/common/http';
import { SQLite, SQLiteObject } from '@ionic-native/sqlite/ngx';
import { BehaviorSubject, Observable } from 'rxjs';

Below is the constructor I am using to try to build the database.

  constructor(private plt: Platform, private sqlitePorter: SQLitePorter, private sqlite: SQLite, private http: HttpClient) {
    this.plt.ready().then(() => {
      const conn = this.sqlite.create({
        name: 'emotions.db',
        location: 'default'
      });
      if (conn == null) throw Error('Failed to create database connection');
      conn.then(() => {
        console.log('Done');
      })
    });
  }

This is run when the app begins, and throws the statement I told it to because the conn == null in this case.

I am unsure why this is occurring, as there are no build errors when doing 'ionic serve'.

This is the wrong way to get a response, just try the way of ionic Documentation,

this.sqlite.create({
  name: 'data.db',
  location: 'default'
})
  .then((db: SQLiteObject) => {
    console.log(db);
  })
  .catch(e => console.log(e));

Unfortunately, this still returns the same error. I am unsure why, but I don't know if the plugin hasn't been installed properly, but since there are no build errors this seems unlikely.

I suggest you remove and reinstall the plugin again.

I am using the same thing in my project and it's working absolutely fine.

as I am seeing you are using service for this, am I right?

I have done these commands: ionic cordova plugin add cordova-sqlite-storage npm install @ionic-native/sqlite After this, it is still not working.
