I was using the CDN release of office-js, but had to change to a local version. After this change, it seems Office.initialize is not being run, which means the add-in doesn't work correctly. On the console, I see the following error:
SCRIPT5022: MicrosoftAjax.js is not loaded successfully.
office.js (18,26767)
The only references to MicrosoftAjax.js that I can find are ASP.NET related, but my project is Typescript/React. Here's how office.js is being loaded in the html:
<!doctype html>
<html lang="en" data-framework="typescript">
<head>
<meta charset="utf-8" />
<meta http-equiv="X-UA-Compatible" content="IE=Edge" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<title>wincross-formatter</title>
</head>
<body class="ms-font-m">
<script src="/assets/office.js"></script>
<div id="container"></div>
</body>
</html>
How can I fix this error?
EDIT:
As per this page, I added the following line just above the office-js script:
<script src="https://ajax.aspnetcdn.com/ajax/jquery/jquery-1.9.0.min.js"></script>
Adding it after the office-js script gives me this error instead of the previous one, and Office.initialize still isn't being called:
SCRIPT5022: Neither the locale, en-us, provided by the host app nor the fallback locale en-us are supported.
FINAL EDIT: That was completely my fault. I didn't copy the contents of office-js/dist recursively.
