global variable cannot be found - window in node.js

Question

I have this Node.js code (Node.js version 8.5.0):

try {
    window.__karma__.complete();
}
finally { 

}

and I am getting this error:

ReferenceError: window is not defined

this seems pretty bizarre, considering this is in a try/catch block.

Anybody know how/why this could happen? I am on Ubuntu, I swear this does not happen on my MacOS machine. I am writing universal/isomorphic code - if window is defined, I should be in the browser.

The error isn't being caught so the runtime will still log it usually even though the flow will continue to the finally block — nem035

yeah you're probably right, pretty weird though, because I swear it wasn't happening on my MacOS machine. — Alexander Mills

As you said, this is in a try/catch block, but you missed the exception catching part.

try {
  window.__karma__.complete();
} finally {}
// -> ReferenceError: window is not defined

This works:

try {
  window.__karma__.complete();
} catch (e) {
  console.log(e)  // -> [ReferenceError: window is not defined]
} finally {}

I think because the catch block was missing, Node.js was simply logging the error without actually throwing the error.
