Sqlite executeSql throws window.angular.element is not a function

Ionic Native
1

Hello,

I have a project in Ionic 4 in which I am trying to use an SQLite database:

this.platform.ready().then(az => {
      this.sqlite.create({
        name: 'ionicdb.db',
        location: 'default'
      }).then((db: SQLiteObject) => {

        db.executeSql('CREATE TABLE IF NOT EXISTS table1 (id INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL UNIQUE, title TEXT)').then(a=> console.log('success'));
    });
});

I tried to run the code above on a device. The databased is created / opened successfully but the executeSql call throws the following error:

vendor.js:51623 ERROR Error: Uncaught (in promise): TypeError: window.angular.element is not a function

Any idea why might this happen?
Thank you!
