Cannot get breakpoints to work in Cloud 9 on AWS

Question

I am using Cloud 9 for JavaScript development. I would like to put breakpoints and inspect my code. Unfortunately, although the code finishes successful and prints the expected statements to the console, I cannot step through the code in debug mode. It never halts at any of the breakpoints.

• I am using node version 11.12.0
• The bug is green
• I set multiple breakpoints on lines that are executed

The execution never halts and I cannot inspect my code. Any ideas of how to fix this?

Thank you!
