Phonegap (Desktop Version) - 500 internal server error on cordova.js

Question

I'm starting my project phonegap. I haven't made changes yet, but it sends the following error in console log:

NetworkError: 500 Internal Server Error - http://192.168.0.103:3000/cordova.js

See image: http://i.imgur.com/7ucV9R1.png

• Why does this error happen?
• Does it affect the operation of the Phonegap?
