Error parsing message

I tried it for amazon and got this error, maybe i need to fill the cookies but im not sure how, can you add an option like "--cookies" ?

Cookies have nothing to do with this process. Can you leave the mpd link and the license url?

Amazon is not supported. They have higher level of security. Try using widevine l3 decryptor browser extension to extract keys and use widevine-dl which is one of my other repos to decrypt the video.
