Event is not updating or Unable to update event

I'm able to add event using this library but when I try to update an event then it's giving error

**Error updating event: DetailedApiRequestError(status: 400, message: Invalid start time.)**

I've tried this static inline code then also I'm getting error

```
startTime.dateTime = DateTime(2025, 06, 05, 03, 15, 00);
endTime.dateTime = DateTime(2025, 06, 07, 03, 15, 00);
```
