How to disable hidden key of wifi network Access Point [Resolved]

I am using Raspbian.

The problem arised when I changed my wifi AP's hidden key by inserting the following line in wpa_supplicant.conf


When I try to view the info of wpa_supplicant file or try to edit it with nano, I just see an empty file.

How can this value of hidden key be returned to as it was initially?

Sorry, It was a silly mistake. I wasn't using root/admin privileges. So, using sudo did all the work.
