When using eb logs, UnicodeDecodeError is thrown and no logs can be viewed

Steps to reproduce

Observed result

The api request returned 200. But it seems the eb cli cannot display the returned logs.

I have the same issue, on linux. As this is my very first experience with eb (and aws for that matter) and my app doesn’t do what I expected it really is a nuisance.

leon@xyz:~/Development/spring-boot-aws-1$ eb logs
Retrieving logs...
ERROR: UnicodeDecodeError - 'utf-8' codec can't decode byte 0xe0 in position 20145: invalid continuation byte

I’m using Python 3.8.5, eb was compiled against a python 3.7.2 that was downloaded by the install scripts. No clue if that matters or not but it may be a library thing.

Note that eb logs -a does work. My terminal $LANG is en_US.UTF-8; maybe that is an issue?

This ishould be fixed in awsebcli version 3.19.3.
