I am trying to implement a feature in frappe Warning popup when doctype is not yet save · Issue #1536 · frappe/frappe · GitHub. I tried editing frappe-bench/apps/frappe/frappe/public/js/frappe/ui/listing.js and just put simple console.log(“Hello world”); I expected that if I go to a table list in a doctype I can see Hello world in browser console but I did not. Do I need to do something. How can I debug javascript in frappe core?
add bench watch in your Procfile and chill
