    It was an issue specific to Azure Functions. The fix was to use a content type of "application/octet-stream".

    res = {
            body: challenge,
            headers: {
                'Content-Type': 'application/octet-stream'
            }
        };

The Dropbox webhook challenge string doesn't contain a BOM, so the Dropbox webhooks service doesn't expect one in the echoed string. That being the case, it does look like something on your side is adding it.

 

Unfortunately, that sounds like an issue with Node or your code itself, so I'm afraid I can't offer much insight. Perhaps someone else here is familiar with it though and can help if you share your code.
