Shell scripting with JQ help

Evening all,

this is my first go at any bash scripting and i'm struggling with handling jquery. I've got the jq library installed and working. i'm working out of Ubuntu and my JQuery looks like this, some info is censored with #.

Code:
{
  "description": "some description 1",
  "fixed_version": "######",
  "link": "https://security-tracker.debian.org/tracker/CVE-#######",
  "name": "CVE-######",
  "package_name": "some package 1",
  "package_version": "####",
  "score": 4.6,
  "score_v3": 9.1,
  "severity": "Medium",
  "vectors": "AV:L/AC:L/Au:N/C:P/I:P/A:P",
  "vectors_v3": "CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N"
}
{
  "description": "some description 2",
  "fixed_version": "#######",
  "link": "https://security-tracker.debian.org/tracker/CVE-#######",
  "name": "CVE-######",
  "package_name": "some package 2",
  "package_version": "#####",
  "score": 4.6,
  "score_v3": 9.1,
  "severity": "Medium",
  "vectors": "AV:L/AC:L/Au:N/C:P/I:P/A:P",
  "vectors_v3": "CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N"
}

What i'd like to do is iterate through this so like so....
Code:
vulnerabilities=$(<"$WorkingDirectory"/vulnerabilities.txt) 
echo $vulnerabilities | $JSONParser -r '.[0].description'

This is the error i'm getting
Code:
jq: error (at <stdin>:1): Cannot index object with number

I've got a web dev background and a bit of PS. Dealing with JQuery in Shell so far has been a nightmare. Can anybody tell me what i'm doing wrong???

Thanks,
DSFX

ROUNDUP-SERVER(1)					      General Commands Manual						 ROUNDUP-SERVER(1)

NAME
roundup-server - start roundup web server SYNOPSIS
roundup-server [options] [name=tracker home]* OPTIONS
-C file Use options read from the configuration file (see below). -n hostname Sets the host name in the Roundup web server interface. -p port Sets the port to listen on (default: 8080). -d file Daemonize, and write the server's PID to the nominated file. -l file Sets a filename to log to (instead of stdout). This is required if the -d option is used. -i file Sets a filename to use as a template for generating the tracker index page. The variable "trackers" is available to the template and is a dict of all configured trackers. -s Enables to use of SSL. -e file Sets a filename containing the PEM file to use for SSL. If left blank, a temporary self-signed certificate will be used. -N Log client machine names instead of IP addresses (much slower). -u UID Runs the Roundup web server as this UID. -g GID Runs the Roundup web server as this GID. -d PIDfile Run the server in the background and write the server's PID to the file indicated by PIDfile. The -l option must be specified if -d is used. -v Print version and exit. -h Print help and exit. name=tracker home Sets the tracker home(s) to use. The name variable is how the tracker is identified in the URL (it's the first part of the URL path). The tracker home variable is the directory that was identified when you did "roundup-admin init". You may specify any number of these name=home pairs on the command-line. For convenience, you may edit the TRACKER_HOMES variable in the roundup-server file instead. Make sure the name part doesn't include any url-unsafe characters like spaces, as these confuse the cookie handling in browsers like IE. EXAMPLES
roundup-server -p 9000 bugs=/var/tracker reqs=/home/roundup/group1 Start the server on port 9000 serving two trackers; one under /bugs and one under /reqs. CONFIGURATION FILE
See the "admin_guide" in the Roundup "doc" directory. AUTHOR
This manpage was written by Bastian Kleineidam <calvin@debian.org> for the Debian distribution of roundup. The main author of roundup is Richard Jones <richard@users.sourceforge.net>. 27 July 2004 ROUNDUP-SERVER(1)
