Uncaught SyntaxError: Unexpected token & in JSON at position 1 at JSON.parse ()

Question

I am trying to parse JSON but it keeps returning

Uncaught SyntaxError: Unexpected token & in JSON at position 1
    at JSON.parse (<anonymous>)

The code looks like this in VS Code:

var result = '{{ bans }}';
  var res = JSON.parse(result)

But in the consol it looks like:

var result = '{&#39;bans&#39;: [{&#39;appealable&#39;: False, &#39;banend&#39;: &#39;Fri, 15 Jan 2021 00:00:00 GMT&#39;, &#39;bannedby&#39;: &#39;parker02311&#39;, &#39;banstart&#39;: &#39;Fri, 15 Jan 2021 00:18:58 GMT&#39;, &#39;id&#39;: 1, &#39;images&#39;: &#39;https://cdn.discordapp.com/attachments/642127559600898058/799867505727504464/Roblox_1_15_2021_11_07_09_PM_2.png,https://cdn.discordapp.com/attachments/642127559600898058/799863972915314688/Roblox_1_15_2021_10_53_30_PM_2.png&#39;, &#39;notes&#39;: &#39;&lt;p&gt;test&lt;/p&gt;&#39;, &#39;reasons&#39;: &#39;Chat Bypassing, Discrimination&#39;, &#39;userid&#39;: &#39;17&#39;, &#39;username&#39;: &#39;test&#39;}, {&#39;appealable&#39;: False, &#39;banend&#39;: &#39;Wed, 20 Jan 2021 00:00:00 GMT&#39;, &#39;bannedby&#39;: &#39;parker02311&#39;, &#39;banstart&#39;: &#39;Sat, 16 Jan 2021 05:46:33 GMT&#39;, &#39;id&#39;: 2, &#39;images&#39;: &#39;https://image.prntscr.com/image/DUQMlOEKTuGDHSkvB4NuRQ.png,https://cdn.discordapp.com/attachments/642127559600898058/799874004457488394/unknown.png&#39;, &#39;notes&#39;: &#39;&#39;, &#39;reasons&#39;: &#39;Chat Bypassing,Discrimination&#39;, &#39;userid&#39;: &#39;202181894&#39;, &#39;username&#39;: &#39;Dagdoubleagaming&#39;}]}';
var res = JSON.parse(result)

I am not sure where all the &#39's came from because the backend looks like:

r = requests.get('http://localhost:5001/get/bans', timeout=5)

        if r.status_code == 200:
            jsonre = r.json()
            return render_template('index.html', name=current_user.username, title='Dashboard', breadcrums=True, bans=jsonre)

The request returns:

    {
      "appealable": false,

Well that works but how do I loop through them and run an action of it? @effprime — parker02311, Jan 17 '21 at 03:42
Can you be more specific? If you are passing the JSON to a template, show your code there — effprime, Jan 17 '21 at 03:43
I am trying to create elements with values from the bans, so like how could I create a element for every object under the "bans" table. — parker02311, Jan 17 '21 at 03:44
your original question has been answered, so I would make a new one :) — effprime, Jan 17 '21 at 03:54

Just taking a shot here, but I took a look here "https://www.w3schools.com/Js/js_json_parse.asp" and I think this might work. I don't think the string is in json format that's why you're getting the error.

var result = '{"bans"}'; var res = JSON.parse(result)
