Expo Calendar alarms issue

Question

I'm trying to add Event in calendar with an alarm 1hour before. I'm using Expo-calendar (ios simulator iOs 13)

Here is my configuration :

 Expo CLI 3.22.0 environment info:
        System:
          OS: macOS Mojave 10.14.6
          Shell: 5.3 - /bin/zsh
        Binaries:
          Node: 10.16.3 - /usr/local/bin/node
          npm: 6.14.5 - /usr/local/bin/npm
        IDEs:
          Android Studio: 4.0 AI-193.6911.18.40.6514223

        npmGlobalPackages:
          expo-cli: 3.22.0

I save the event when a user clicks on a button, here is my main function :

The calendar creation works / the event creation (without alarm) works

addEventCalendar = async (itemEventData) => {
        console.log('add event');

        const { status } = await Calendar.requestCalendarPermissionsAsync();
        if (status === 'granted') {

            //creation du calendrier
            let appCurrCalendar = await this.getAppCalendarSource();
            console.log(' ----- ');
            console.log(' appCurrCalendar : ' + JSON.stringify(appCurrCalendar));
            console.log(' ----- ');
            let currCalendarId;

            if (appCurrCalendar === undefined) {
                console.log('no cal --> create');
                currCalendar = await this.createCalendar();

                console.log('new cal id = ' + JSON.stringify(currCalendar));

                currCalendarId = currCalendar;

            } else {
                console.log(' cal  --> Trouvé');
                console.log(' cal title = ' + appCurrCalendar.title + " --> id : " + appCurrCalendar.id);
                currCalendarId = appCurrCalendar.id;
            }


            var detailsEvent = {
                title: itemEventData.titre_flyer,
                startDate: moment(itemEventData.event_date + " " + itemEventData.event_hdeb).format("YYYY-MM-DD[T]HH:mm:ss.sssZ"),
                endDate: moment(itemEventData.event_date + " " + itemEventData.event_hfin).format("YYYY-MM-DD[T]HH:mm:ss.sssZ"),
                timeZone: Localization.timezone,

                location: itemEventData.lib_agence + " " + itemEventData.adresse_agence + " - " + itemEventData.ville_agence + " " + itemEventData.cp_agence
            }

            

            var idEvent = await Calendar.createEventAsync(currCalendarId, detailsEvent).catch((error) => console.log("ERROR create EVENT  >>> " + JSON.stringify(error)));


            console.log('event created : OK');
            console.log('event created : ' + JSON.stringify(idEvent));

            /************* IF I TRY TO ADD AN ALARM APP CRASHED *******************/
            /*
            console.log('event update start ');

            await Calendar.updateEventAsync(idEvent, {
                alarms: [{ relativeOffset: -60 } ],  //reminder 60 minutes before
                timeZone: Localization.timezone
            }).catch((error) => console.log("ERROR update Event  >>> " + JSON.stringify(error)));

            console.log('event update end ');
            */
            /************* IF I TRY TO ADD AN ALARM APP CRASHED *******************/
            }
        }

I read a lot of forums but didn't undestand why... App crashed on alarms update.

this is the error response :

    ERROR update Event  >>>
