Hi Jota,
I have just tried to upload a pdf file using a upload menu and selecting resource type as document.
I was not able to get preview of pdf when i click on pdf thumbnail.
I have executed the bnsupport tool and bundle was uploaded successfully to the Bitnami servers. Please check the following code for further analysing.
