I have follow all steps as described but got this error when I try to connect an URL.
Please look into this error, what I am doing wrong. If you have any other example implementing pywb?
I need to connect to remote URL with headless chrome (Like co-browsing).

URL :- /api/flock/start/UVALFHP74PWF2NZN5IY3QL4A

Payload:-

"SCREEN_WIDTH": 1120,
"SCREEN_HEIGHT": 312,
"AUDIO_TYPE": "webrtc",
"REQ_ID": "UVALFHP74PWF2NZN5IY3QL4A"
}

you should do this before docker-compose up -d :

docker pull oldwebtoday/remote-desktop-server:latest
