Error In installing ERPNext stack in Ubuntu 20.04 : ansible-playbook error

Fixed the error… It was indeed an NPX issue… Nginx needed to be restarted as the old(past) version had some dependencies which needed to be reloaded…
For Future Reference…
#In the Bench directory
npm init
npm update caniuse-lite browserslist
yarn install
yarn upgrade caniuse-lite browserlist

That should particularly fix the bench start at restart problem
