Hi everyone. I have a next horrible Error of debug mode javascript stage in WebStorm 2018 version. For example I want to set my debug Javascript mode into my html file wiith name int.html. And according to that, I including a one application javascript file bootstrap.js. And that file need to make fired on checkpoint in my debug when I try to connect in debug mode Javascript on path – http://localhost:63342/MatrixDraw/index.html. But in result after run my debug mode I have a next error and warning message : “Waiting for connectionto localhost:59459. Plesse make sure that the browser was started successfully with remote debbugging port opened. Port cannot be opened if Chrome having the same User Data Directory is already launched.” I hope that the programeers and support service personal of Jetbrains development make resolve my problem and to set me advise, “How do resolve javascript debug mode?”.
