Describe the bug

Using jard and it printed this message in my console. Jard worked fine tough:

Environment (please complete the following information):

OS: MacOs Catalina 10.15.6
iTerm2 (tested with and without Overmind)
Output when you run tput colors in your terminal: 256
Output when you run echo $TERM in your terminal: xterm-256color
Output when you run stty:
speed 38400 baud;
lflags: echoe echok echoke echoctl pendin
iflags: iutf8
oflags: -oxtabs
cflags: cs8 -parenb
Do you use tmux/screen or similar tty multiplexer?: I use Overmind, but I tested with a vanilla rails s in a new tab and it happens just the same
