I had exactly the same error, also unraid.
So I decided to print out the request that the stacktrace is telling us that it can't decode and I saw that the response from trakt gave a http status code 403 back.
So I went back to the readme file and saw that in the previous step, we had to create an app in trakt.tv and give it the clientId and clientSecret which I did not enter in my config on my new install.
So probably you guys missed that step too.
After filling in the clientId and clientSecret I was able to succesfuly run traktarr trakt_authentication
