Yeelight RGB v2 with Xiaomi Mi IO Binding

I’m trying to connect my new Yeelight RGB v2 bulb using the Xiaomi Mi IO Binding but I’m having trouble (I think becuase of the token thing) controlling it.
I have it configured properly and I see the lamp as Online, but every time I send it a command an error similar to this is logged:

[WARN ] [rnal.transport.MiIoAsyncCommunication] - Send command '{"id":7631,"method":"get_prop","params":["power","bright","delayoff","ct","color_mode"]}'  -> 192.168.XXX.YYY(Device: 0538C102) gave error Given final block not properly padded

I followed this guide to extract the token (method 2 - Packet sender):

The response I receive is:

21 31 00 20 00 00 00 00 05 38 C1 02 00 00 00 1F C1 C9 95 80 1D 9F 1E D4 AE D0 1B C7 62 C6 47 7F

So the token is C1C995801D9F1ED4AED01BC762C6477F, right?

Thank you!
