intern serve command is not working after reporters added in intern.js - intern

Question

I have installed intern globally and on command prompt 'intern serve' commands works fine. However after adding reporters property in intern.js if I run 'intern serve' command then nothing happens and command stuck as below saying "Running runner tests…".
D:\start>intern serve
Running runner tests…
Here is my intern.js file

There are a several issues here:
The message "Running runner tests...' is only emitted by the Combined reporter, not the Runner reporter.
The Runner reporter is intended to output to the console; giving it an HTML filename will just output text to an HTML file (it won't generate an HTML report).
The reporter config doesn't actually do anything when you're running intern serve because intern in serve mode is just serving files (not running tests).
Is your intern.js file in tests\? Intern assumes the project directory looks like:
D:\start
tests\
intern.js
node_modules\
intern\
When running intern serve in D:\start, intern will look for its config file in tests\intern.js.
