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

NAME
tracker-status - Report the state of all data miners SYNOPSIS
tracker-status [OPTION...] DESCRIPTION
tracker-status shows the status of all miners installed. It also allows pausing and resuming of miners. For tracker-store state, you need to use tracker-control OPTIONS
-?, --help Show summary of options. -f, --follow Follow status changes as they happen. This requires Ctrl+C to stop and return to the command line. Each new status is put on a new line. To get more information, you can use --detailed with this. -d, --detailed For the most part, this purely provides a timestamp with each status update to follow WHEN changes happened. -s, --list-common-statuses This will list statuses most commonly produced by miners and the store. These statuses are not translated when sent over D-Bus and should be translated by each application. These are not considered static and are subject to change at any point. Additionally, these statuses are not the only ones which may be reported by a miner. There may be other states pertaining to the specific roles of the miner in question. -l, --list-miners-running This will list all miners which have responded to a D-Bus call. Sometimes it is helpfult to use this command with --list-miners- available. -a, --list-miners-available This will list all miners which are available even if they are not running at the moment. -i, --pause-details For listing all miners which are paused and the reasons for being paused, you can use this. It will also display the application that requested the pause too. -m, --miner=MINER This argument is used with --pause and --resume to say which miner you want to pause or resume. You can use the full D-Bus name, e.g. org.freedesktop.Tracker1.Miner.Files OR you can use the suffix, e.g. Files -p, --pause=REASON The REASON here is useful to know WHY the miner should be paused. A miner can be paused many times by multiple applications. Only when all pauses have been resumed will it continue. If successful, a cookie will be given to uniquely identify the request. This cookie is used to resume the pause at a later stage. -r, --resume=COOKIE The COOKIE is given by a successful --pause command. It is a number which identifies each pause request. When all pauses have been resumed, the miner will resume working. -V, --version Print version. SEE ALSO
