Somehow it is working but i get this error message.
I save 4 database with an await in a row. That causes the problem above but i dont know why?

Hi @apppro123, I am unable to diagnose the problem. Can you help to clarify the error? It'd be helpful to have:

• A screenshot of the error
• Snipped part of code that the issue appear
• and Expected behavior

Thank you!

[apppro123]

I will write you tomorrow!

Thank you.

Is #19 related to this thread?

[apppro123]

No. #19 is just for Android 7 and lower but #18 is in every version.

snippet of code which is responsible for error (before i insert in every database with .insert({...}, false), so save is false)
await Alarm.save();
await Recurrence.save();
await OtherCalendar1.save();
await CalendarEvent.save();

Expected behaviour no error :)
But as i already mentioned i didnt noticed that this effects the db, everything else works as expected but is fires an error.

@apppro123, were the data successfully inserted?

[Hieu Nguyen (Jack)]

The error Unable to write data will appear when it doesn't find the document name (for example Calendar or Alarm). Or when calling Calendar.insert without any records.

I should be able to make the error message more clear and prevent calling insert method without any records.

Besides, it is a good practice to wrap code in try catch block when using await. I think it helps manage the error easier. Otherwise, it will throw an error and crash the app.

For example, you can wrap the above code like this:

try {
    await Alarm.save();
    await Recurrence.save();
    await OtherCalendar1.save();
    await CalendarEvent.save();
} catch(error) {
    // console.log(error)
}

(I always try to make my answer clear. Sorry if you find the answer contains things you already know)

Hi @apppro123, have you able to work this out yet?

[apppro123]

Yes, i dont get errors any more. So i think it has worked! :)
