"Failed to recognize file format" error

Followed the steps to get the CBC from my browser, then tried to use it at a docker container where I have cloned the repo and installed all needed dependencies (jq, curl, dialog, mpv):

Any idea what am I doing wrong?

Also tested to get the CBC following the great Shellscript from this comment but with exactly the same issue with same error log.

I solved, the problem was that hexdump was missing, to fix, in a debian based container, just:
apt-get install -y bsdmainutils
