I have installed dataiku, everything seems to work fine except that when connecting to the UI, the following message appears : "Oops: an unexpected error occured
If this happens again, please use Feedback to tell us more about what you were doing.

NullPointerException
HTTP code: 500, type: java.lang.NullPointerException".

Nginx logs show those errors : " nginx: [alert] could not open error log file: open() "/var/log/nginx/error.log" failed (13: Permission denied)

    You might have a permission error.

    You should install and run DSS with the same unix user. More info in the doumenation: http://doc.dataiku.com/dss/latest/installation/new_instance.html

    I hope that helps,

    Thank you Jeremy. I'll recheck this tomorrow but if I remember correctly the user for the installation and the running process were the same. I'll give you confirmation when I can.

    Kind regards,

    Okay, I just figured out the problem. It was a licence issue. I had copied and pasted the licence code into a text document that would serve me as the licence entry at the moment of installation. However, Dataiku wouldn't be able to parse it correctly and wouldn't be able to send the right requests to the server to get the corresponding configuration for the enterprise version of Dataiku.
