It appears that events created from Microsoft Bookings (https://learn.microsoft.com/en-us/microsoft-365/bookings/bookings-overview?view=o365-worldwide) have a different schema.

Here, for example, a SyncFolderItemsResponse containing an update of Booking type.

                        }
                    }
                }
            }
        }
    }
}

This causes the parsing to fail. Depending on the API called, we see either The type of the object in the store (Booking) does not match that of the local object (CalendarItem). (when using LoadPropertiesForItems) or Cannot read property of null (reading 'LoadFromXmlJsObject') (when using SyncFolderItems).
