Bench Start Issue

I am trying to start the bench but it exits out. Why?

Looks like your redis and/or supervisor subsystem is stopped. This might help

sudo supervisorctl restart

When you run bench start, bench is meant to redis and/or supervisor start on its own. It looks like there’s an error with yarn building the site.
If you (@Pratik_Vaity) could post the full bench start log, that would be appreciated.
