无法在发送加载项清单时在 Outlook 中添加 AppDomain

Question

I'm relatively new to developing Outlook add-ins, and am facing a problem developing an on-send add-in.

I am trying to do an ajax call from inside my on-send add-in like this:

$.ajax({
    url: "https://XXXXXXX.dev:9999/createMeeting",
    data: JSON.stringify(result),
    contentType: 'application/json',
    type: 'POST',
    dataType: 'json',
    error: function(xhr, status, error) {
        console.log("ERRROR", error)
    }
}).done(function(data) {
    console.log("DONE ", data)
});

My manifest looks like this:

<?xml version="1.0" encoding="utf-8"?>

</OfficeApp>

But I keep getting this error when I try to add the add-in

This app can't be installed. 
The manifest file doesn't conform to the schema definition. 
The element 'OfficeApp' in namespace 'http://schemas.microsoft.com/office/appforoffice/1.1' has invalid child element 'AppDomains' in namespace 'http://schemas.microsoft.com/office/appforoffice/1.1'. 
List of possible elements expected: 'Id' in namespace 'http://schemas.microsoft.com/office/appforoffice/1.1'... 
The element 'OfficeApp' in namespace 'http://schemas.microsoft.com/office/appforoffice/1.1' has invalid child element 'AppDomains' in namespace 'http://schemas.microsoft.com/office/appforoffice/1.1'. 
List of possible elements expected: 'Id' in namespace 'http://schemas.microsoft.com/office/appforoffice/1.1'.

According to the docs , The AppDomains element must be a child of the OfficeApp element. Am I doing something wrong?? Thanks in advance!

EDIT: This occurs on Outlook OWA (web) and Windows application. Have not verified on other platforms.

Answer 1

It seems like the problem is caused due to the order in which you are adding the elements in manifest. As manifest file follows the schema xmlns="http://schemas.microsoft.com/office/appforoffice/1.1" it expects elements in certain order mentioned here . If you follow the order of elements mentioned in sample manifest it should work fine.

Updated the links again.

Posting an example in case anyone else has the same problem.
