This is a string, you need to use bytes.

data = bytes("GET_LIST",'utf8')

Python 3 uses unicode strings by default.
Many low level functions need a byte array instead.
Usually you can just wrap your original string in
a bytes call with utf8. If you are using more complex
strings you may need to start using explicit encode/decode.
But in this case it shouldn't be needed.
