auth login exits with status 0 even for a non-working URL
Steps to reproduce
Note the literal use of example.com here; don’t replace it with an actual, working MM instance URL.
# /usr/bin/sudo -u mattermost /usr/local/bin/mmctl auth login http://example.com --name example --access-token 123456890abcdefghijklmnopq`
# echo $?
What I expect happen
For a non-zero exit status to be printed.
What happens instead
