How to avoid "skipped by smartStep" in visual studio code

I have a huge server application (nodeJs) with many files and functions. I try to debug it via Visual Studio Code. I put break point to some function which I assume will be called in proper time and run debug. But debugger stopped in some "random" place of node modules files and say - "Skipped by smartStep". What is it? I don't want to have this unexpected behaviour. If my function isn't call, I just want that the program goes through the chain and skipped it. How to turn off "smart step" and what of is this feature about?
