Javascript 使用expo日历。createEventAsync（）返回失败

我使用Calendar.createEventAsync（）创建事件

SDK Version: “expo”: “~38.0.8”,
“expo-calendar”: “~8.2.2”,
Platforms(Android/iOS/web/all): iOS

在我尝试创建每月重复事件之前，它工作得很好。我知道问题来自“复发”。但我不知道怎么了

当createEvent for weekly Recurrential时，它通过以下recurrentRule运行良好：

const taskId = await Calendar.createEventAsync(
task.calendarId,
{
title: task.title,
startDate: task.startDate,
endDate: task.endDate,
alarms: [{relativeOffset: task.alarmTime}],
allDay: task.allDay,
notes: task.notes,
timeZone: task.timeZone,
location: task.locationAddress,
recurrenceRule: task.recurrenceRule
}
)

recurrentRule: Object {
“daysOfTheWeek”: Array [
Object {
“dayOfTheWeek”: 2,
},
Object {
“dayOfTheWeek”: 3,
},
],
“frequency”: “weekly”,
“interval”: 1,
}

但当我通过以下重现规则创建每月事件时失败：

const taskId = await Calendar.createEventAsync(
task.calendarId,
{
title: task.title,
startDate: task.startDate,
endDate: task.endDate,
alarms: [{relativeOffset: task.alarmTime}],
allDay: task.allDay,
notes: task.notes,
timeZone: task.timeZone,
location: task.locationAddress,
recurrenceRule: task.recurrenceRule
}
)

recurrentRule: Object {
“daysOfTheWeek”: Array [
Object {
“dayOfTheWeek”: 2,
},
Object {
“dayOfTheWeek”: 3,
},
],
“frequency”: “weekly”,
“interval”: 1,
}

有人能告诉我每月复发的原因吗。谢谢
