Salt-cp Times wrong UnicodeDecodeError - Codes Helper

problem description

uses salt-cp to copy a compressed package of tar.gz, which reports an error after execution, but the file has been fully transferred to the minion side.

the environmental background of the problems and what methods you have tried

I tried to change the code environment of python2.7 to UTF-8, and restart salt-master and salt-minion, but it didn"t work.
