Duplicity backup to onedrive client error
<p>I'm trying to make backup of files on my computer in onedrive with duplicity.
I have installed all dependencies, when running duplicity there is the auth link generated which I must open in browser and than in duplicity after giving permissions for app paste the return url.</p>

<p>I do all this steps but duplicity is returning me</p>

<p>It looks like there is no app with ID which duplicity generate auth link with.
But when I go to the link provided by duplicity I see that "Duplicity is asking for permissions".</p>

<p>So should I add my own app and in some way provide its id to duplicity? (I was searching how to do it but without result) or is it a duplicity bug?</p>
