How to synchronize debug js FrontEnd in WebStorm?

Question

IntelliJ IDEA

Used Intellij IDEA 2017 and everything was fine. But after updating to 2018, the breakpoint is not stuck in the src file, but in the file from localhost. Those. I have a src/main.js file in which the breakpoint is located, and when it is stuck into it, the localhost:8000/main.js file opens in the ide.
map files are set up correctly.
Specify Local Path also points to the src file.
A similar story is repeated in the latest WebStorm.
Operating system Linux Mint 18.
Chrome Version 68.0.3440.106 (Official Build) (64-bit).
JetBrains IDE Support version 2.0.9
What could be the problem and how to fix it?
