Answer 1

I have the same in an Angular 6 app, but common.js is actually part of some chrome extension, not the Angular app. It's part of the StandsApp ad blocker: https://www.standsapp.org/

Answer 2

It's like what Jonesie said, i have other node.js app and it showing

"Uncaught ReferenceError: $st is not defined at common.js:263"

. If you want the error message go away, just turn of the extension.
