I'm new to nodeJs and want to debug a NodeJs app and since mostly developing java apps, installed Eclipse for java developers 2020-06. I can run the app by write clicking on package.Json and choose run as> npm. but when I wanted to debug this app, and opend debug as, can not find npm launch configuration. I have Node program in "debug As" menu instead, but if I click on that, I'll get 'Url must be a string error.

      throw new TypeError('Url must be a string. Received ' + strArray[0]);
      ^
