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-search - Search all content for keywords SYNOPSIS
tracker-search [OPTION...] EXPRESSION [EXPRESSION...] DESCRIPTION
tracker-search searches all indexed content for EXPRESSION. The resource in which EXPRESSION matches must exist (see --all for more infor- mation). All results are returned in ascending order. In all cases, if no EXPRESSION is given for an argument (like --folders for example) then ALL items in that category are returned instead. EXPRESSION One or more terms to search. The default operation is a logical AND. For logical OR operations, see -r. OPTIONS
-?, --help Give a short help message. -l, --limit=N Limit search to N results. The default is 512. -o, --offset=N Offset the search results by N. For example, start at item number 10 in the results. The default is 0. -r, --or-operator Use OR for search terms instead of AND (the default) -d, --detailed Show the unique URN associated with each search result. This does not apply to --music-albums and --music-artists. -a, --all Show results which might not be available. This might bebecause a removable media is not mounted for example. Without this option, resources are only shown if they exist. This option applies to all command line switches except --music-albums and --music-artists. -f, --files=EXPRESSION Search for files of any type matching EXPRESSION (optional). -e, --folders=EXPRESSION Search for folders matching EXPRESSION (optional). -m, --music=EXPRESSION Search for music files matching EXPRESSION (optional). --music-albums=ALBUM Search for music albums matching ALBUM (optional). --music-artists=ARTIST Search for music artists matching ARTIST (optional). -l, --images=EXPRESSION Search for images matching EXPRESSION (optional). -v, --videos=EXPRESSION Search for videos matching EXPRESSION (optional). -t, --documents=EXPRESSION Search for documents matching EXPRESSION (optional). -e, --emails=EXPRESSION Search for emails matching EXPRESSION (optional).
