Error uploading assets in AEM 6.4 GA
Hi masters!
I've an issue when uploading assets to an AEM 6.4 GA vanilla installation.
With the admin user, it works perfect.
But I've created a user and added to the 'DAM Users' group. With this new user, when I upload an asset, the UI shows an error (tried with different file extensions):


If you refresh the page, the asset is perfectly loaded. By the message, it seems like the browser is trying to load the asset 2 times at the same moment).
Same behaviour with Chrome and Firefox.
I've googled but I can't find any reference. Could you reproduce it? Any idea?
Thank you very much! Kind regards,
J.
