Profile tab is not showing

Hi!!
I'm having some memory issues in a nodeJS application that is currently on production so I'm trying to search for a way to detect and prevent it.. I came across this tutorial but when I open the debug page the profile tab is not showing ( after I've followed the steps from the tutorial ). Am I doing something wrong?

Thanks!

The report names no repository file, test, Node version, or browser. First reproduce the tutorial steps and inspect the debug page in the same environment; done means determining why the Profile tab is absent and recording a verified fix or compatibility requirement.
