help getting key with this video

[Maxw2191]

I got PSSH and lic url but it seems incomplete as I receive this error: Ciphertext with incorrect length.

PSSH: AAAAUnBzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAADIIARIQGP X0Bw8GeH91JXQMCoSdUxoMaW5rYWVudHdvcmtzIgoxMTY1OTAy NTQwKgJIRA==

Lic url: https://drmproxy.viu.com/api/license/1165902540/

I also find this in the payload but don't know how to use it

authorization: a1edb043cfa9d15ece39c561109610MqN5I1xNaqQeGwM41tBr kC9XGNfVdqPoJHtm1pk9OwhogSSsaOiKpBRJu6ITumAi8RBIwE LRp1STHicHvOGfJ5ygeYNgfBbgd8y56g
