### Provide a description that is worded well enough to be understood

Github newbie here:
The Parler extractor seems busted. I was able to go into Chrome's F12 code inspector thing to find the downloadable URL after clicking the thumbnail, but I was not able to get the extractor to work via the post's URL.

### Provide verbose output that clearly demonstrates the problem

- [X] Run **your** yt-dlp command with **-vU** flag added (`yt-dlp -vU <your command line>`)
- [X] Copy the WHOLE output (starting with `[debug] Command-line config`) and insert it below
