Debug application built on local Meteor packages

How can one debug local Meteor packages? I mean by setting up breakpoints within the packages in the IDE just like in any other codebase. Please don’t dismiss the question with an offer to scatter temporary “debugger” statements all over the codebase as that’s not really a viable replacement for registering breakpoints in the IDE for many obvious reasons. I work on a project built almost entirely on local Meteor packages to enable custom modular deployment of the application for different clients and breakpoints don’t get picked up within packages for some reason and application won’t stop on them which is a crucial pain point of the development. Am I missing something about the setup? Is this something that simply doesn’t work in Meteor? (I sure hope that is not the case)

None of the existing topics here seem to have a satisfactory answer…
Appreciate any suggestions - thanks in advance!
