Could you post an example repro? It looks like you have a test case with multiple browser.pause() calls.

I don't know if @shawon-barua case is same, but on my end the problem is caused by error thrown from debuggerCommons.js:

@maciejtreder

I think your error is related to #4390 because, what I assume, you use NodeJS 8

[maciejtreder]

@wswebcreation I resolved my issue by downgrading node.js from 8+ to 6+. The problem was probably related to that protractor is calling node debug under the hood which is deprecated:

(node:75080) [DEP0068] DeprecationWarning: `node debug` is deprecated. Please use `node inspect` instead.

Dupe of #4307

Any idea why this issue is still not resolved?
