GetItem xml request using makeEwsRequestAsync() in Outlook for Mac has stopped returning a response

Question

Outlook for Mac: 16.24 (19041401)

I'm making a getItem request using makeEwsRequestAsync in Outlook for Mac and the callback does not contain a response, (status == succeeded, value is null). The same request from OWA/Outlook 2016 contains a valid xml response. I'm using the GetItem request to retrieve a changekey.

Why is there a difference in behavior here?
