Access forbidden error when I try to access Cloudant data in CSV format, using a URL

I wanted to use the 'List' and 'View' options in Cloudant to convert the JSON documents present in my view, to csv format. I have created the 'List' function for the same. After that, I tried to access/download the data in csv format, using [this URL][1].

https://8eb92b78-aca3-4bdf-bd96-a0482df2b60c-bluemix.cloudant.com/_design/submittedView/_list/first-format/submitted-view?include_docs=true

These are the details used in the URL :

Host name : 8eb92b78-aca3-4bdf-bd96-a0482df2b60c-bluemix.cloudant.com

Name of design document used : submittedView

Name of list used : first-format

Name of view : submitted-view

The error that I get when trying to access the data is as follows :

{"error":"forbidden","reason":"server_admin access is required for this request"}

Note : I generated an API key and gave it the following access.

  _admin  
  _reader    
  _writer   
  _replicator

However, I get the same error even when I try to access the URL with this API key. Please help me understand what I can do to resolve this issue. My primary objective is to download the data present in the Cloudant db, in CSV format. Any help or advice will be much appreciated!
