Can't remove email address from EWS contact - ews-javascript-api

Question

I'm using the ews-javascript-api to manage my EWS contacts on an exchange server.
I'm trying to update a contact object by removing an email address.
I've followed this blog post and it's got me most of the way there. However, when I remove the ExtendedProperty's for EmailAddress1 the ews-javascript-api throws an exception due to an HTTP 500 coming back from the EWS soap request to update a contact. Looking at the SOAP request, I can see that there is an empty FieldURI which is what the response error is complaining about.
Here is my soap request
<soap:Envelope

</t:DeleteItemField>
</t:Updates>
</t:ItemChange>
</m:ItemChanges>
</m:UpdateItem>
</soap:Body>
And here is the soap response
<?xml version="1.0" encoding="utf-8"?>
<s:Envelope

<t:Violation>The required attribute 'FieldURI' is missing.</t:Violation>
</t:MessageXml>
</detail>
</s:Fault>
</s:Body>
And finally here is the exception that the javascript api throws.
"Exception
at UpdateItemRequest../node_modules/ews-javascript-api/js/Core/Requests/ServiceRequestBase.js.ServiceRequestBase.ProcessWebException (https://sr1.genband.com/genlync/bundle-electron.js:44707:36)
at https://sr1.genband.com/genlync/bundle-electron.js:45557:41
at <anonymous>"
Finally I'll mention that I can remove an email address without removing any extended properties with the following function.
response.EmailAddresses._setItem(ews.EmailAddressKey.EmailAddress1, address.value);
However, the problem with this is, while it looks like it works, if I try to edit that contact on my outlook web interface, I get an error about some property mismatch. Looks like if I don't remove those extended properties when deleting an email, then they stay around and cause issues for other clients.

Answer 1

this should work in 0.9.3 version, available starting 0.9.3-dev.1 which is ews-javascript-api#next currently.
