Error message is not formatted properly

What's going wrong?

While stopping a pm2 --no-daemon process it prints some console message, one of them prints %s directly without putting process name in it.

[Watch] Process name %s is being stopped so I won't restart it

How could we reproduce this issue?

Start any nodejs script with pm2 start app.js --watch --no-daemon , and then stop it by sending CTRL + C Signal.
