trusted-replace-outbound-text

[uBlock-user]

I'm testing this filter - www.reddit.com##+js(trusted-replace-outbound-text, JSON.stringify, /^.*csrf_token.*$/, '{"source:global","screen":{"height":0,"width":0}","view_stats":{"comments":0}}') as a fix for https://github.com/uBlockOrigin/uBlock-discussions/discussions/819#discussioncomment-7218569 and it does what I want it to do, but server responds with 400 status(Internel server error), is it because this payload is not in JSON format ? If yes, then how to convert to JSON format ? Internal Server error issue fixed with this version --

www.reddit.com##+js(trusted-replace-outbound-text, JSON.stringify, /^.*csrf_token.*$/, '{"source": "global","screen": {"height": 480, "width": 840},"view_stats":{"comments": 100}}')

But comments won't load still. How to fix that ?

If I use www.reddit.com##+js(trusted-replace-outbound-text, JSON.stringify, '/"csrf_token":.*?,/'), the comment loads, so this means the server expect something in the payload to be there in order to respond properly.

[uBlock-user]

Does this pattern remove the entire payload ?

This is their script --

if (s?.ok) {
      "basic" === s.type && s.headers.has("x-verified-res") && ((e, t = hn) => {
         if (e.includes("global") && e.includes("view") && e.includes("screen")) {
            for (let n = 0; n < t.length; n++)
               if (!e.includes(t[n])) return !1;
            return !0
         }
         return null
      })(i) && (Ur || (Ur = document.querySelector("shreddit-app")), Ur)?.resolvePendingRequests();
      const e = s.headers.get("x-set-loid") || void 0,
         t = s.headers.get("x-set-session") || void 0;
      window.dispatchEvent(new CustomEvent("v2-events-sent", {
         detail: {
            loid: e,
            session_tracker: t
         }
      }))
   } 

They're looking for presense of screen|view|global in the request body.

Now it's:

if (d?.ok) {
  'basic' === d.type &&
  d.headers.has('x-verified-res') &&
  (
    (e, t = hn) => {
      if (
        e.includes('global') &&
        e.includes('view') &&
        e.includes('screen')
      ) {
        for (let n = 0; n < t.length; n++) if (
          !e.includes(t[n].field) ||
          t[n].validatePresence &&
          e.includes(`"${ t[n].field }":""`)
        ) return !1;
        return !0
      }
      return null
    }
  ) (s) &&
  (Fr || (Fr = document.querySelector('shreddit-app')), Fr) ?.resolvePendingRequests();
  const e = d.headers.get('x-set-loid') ||
  void 0,
  t = d.headers.get('x-set-session') ||
  void 0;
  window.dispatchEvent(
    new CustomEvent('v2-events-sent', {
      detail: {
        loid: e,
        session_tracker: t
      }
    })
  )
}

Seems that they are checking if there's an empty value. For now it's only on "page_type":

[uBlock-user]

Now we need to add placholder values and cannot keep them empty

[D4niloMR]

Yes, let's hope they don't purposely break reddit for uBO users...
