SMS cordova plugin INTENT is not working

Hello everyone

I am using Ionic 4 to build an app that is meant to send an emergency SMS, therefore I need it to be sent programatically without entering into the native SMS app.

Im using the following code:

async sendSMS(){
    this.androidPermissions.checkPermission(this.androidPermissions.PERMISSION.SEND_SMS).then(
      result => console.log('Has permission?'+result.hasPermission),
      err => this.androidPermissions.requestPermission(this.androidPermissions.PERMISSION.SEND_SMS )
      );
    var options = {
            replaceLineBreaks: true, // true to replace \n by a new line, false by default
            android: {
                //intent: 'INTENT'  // send SMS with the native android SMS messaging
               intent: '' // send SMS without opening any other app
            }
        };
        try{
        await this.sms.send(this.phoneNumber.toString(),this.textMessage,options);
        console.log("sent");
        this.mostrarToast("mensage sent");
      }
      catch(e){
        console.log(JSON.stringify(e));
        console.log(e);
        this.mostrarToast(e);
      }
  }

Nevertheless I get this error in my logcat
