Expanding singleValueExtendedProperty not working when retrieving Event details

问题

I am trying to retrieve custom property value for an event using Microsoft Graph. The custom property was created by an Outlook Office.js Add-ing

Here is request

/v1.0/me/events/{id}?$expand=singleValueExtendedProperties($filter=id eq 'String {00020329-0000-0000-C000-000000000046} Name myCusProp')

This returns a successful response from Graph but it does not return the singleValueExtendedProperty. The Outlook add-in, however, is still able to retrieve the property value from the same Event.

----Update 1 - office.js code-----

This is office-js/outlook-add-in code reference above. The custom property value can be read here without an issue.

const item = Office.context.mailbox.item;

item.loadCustomPropertiesAsync(asyncResult => {
    if (asyncResult.status == Office.AsyncResultStatus.Succeeded) {
        let customProps = asyncResult.value;
        customProps.set("myCusProp", "google.com");
        customProps.saveAsync(asyncResult => {
            if (asyncResult.status == Office.AsyncResultStatus.Succeeded) {
                item.loadCustomPropertiesAsync(asyncResult => {
                    const customProps = asyncResult.value;
                    const myCusProp = customProps.get("myCusProp");
                })
            }
        });
    }
});

回答1:

From documentation:

id eq 'String {00020329-0000-0000-C000-000000000046} Name cecp-<add-in id from manifest>'

Instead of myCusProp use cecp-/* add-in id from manifest */

Add-in id is the guid from manifest, this response has a custom properties as JSON.
