Hi Community, any one facing issue when calling onesignal library the script like skip from executed or not properly running? Because i facing some issue on onesignal that certain phone look onesignal no properly running so we cannot get the deviceid. certain phone working fine. i still don’t have clue what happen.

Below is my code.

await this.oneSignal.startInit(environment.onesignal.appId, environment.onesignal.googleProjectNumber);
this.oneSignal.setSubscription(true);
this.oneSignal.inFocusDisplaying(this.oneSignal.OSInFocusDisplayOption.Notification);
this.oneSignal.enableSound(true);
this.oneSignal.enableVibrate(true);
await this.oneSignal.endInit();

    this.oneSignal.getIds().then((data) => {
      console.log('iddddd', data);
      localStorage.setItem('fcm', data.userId);
      
    }).catch((e) => {
      console.log(e);
    });

Try this:

this.platform.ready().then(() => {
    this.oneSignal.getIds().then((data:any) => {
      console.log('iddddd', data);
      localStorage.setItem('fcm', data.userId);
      
    }).catch((e) => {
      console.log(e);
    }); 
});

Don’t forget to import the Platform and add it to your constructor.

Yes, actually is similar like your suggestion here the full one:

this.platform.ready().then(() => {
      this.statusBar.backgroundColorByHexString('#ffcd40');
      this.splashScreen.hide();
      setTimeout(async () => {
          await this.oneSignal.startInit(environment.onesignal.appId, environment.onesignal.googleProjectNumber);
        this.oneSignal.setSubscription(true);
        this.oneSignal.enableSound(true);
        this.oneSignal.enableVibrate(true);
        await this.oneSignal.endInit();
         this.oneSignal.getIds().then((data) => {
         console.log('iddddd', data);
         localStorage.setItem('fcm', data.userId);
      
         }).catch((e) => {
            console.log(e);
        }); 
     },5000);
});

and also its not go to catch part to show error. its like just skipped.

      this.splashScreen.hide();
       this.oneSignal.startInit(environment.onesignal.appId, environment.onesignal.googleProjectNumber);
        this.oneSignal.setSubscription(true);
        this.oneSignal.enableSound(true);
        this.oneSignal.enableVibrate(true);
        this.oneSignal.endInit();
        setTimeout(() => {
         this.oneSignal.getIds().then((data) => {
         console.log('iddddd', data);
         localStorage.setItem('fcm', data.userId);
         }).catch((e) => {
            console.log(e);
        }); 
     },5000);
});

Try this change in your code.
