Runtime error: Cannot read property 'appendChild' of null(…)

[kittykatattack]

I have some code that compiles and runs fine in elm reactor.
However, when I run code the code with elm-webpack-starter I'm getting this runtime error:

Cannot read property 'appendChild' of null

The problem code is parentNode.appendChild(appNode); from this block of ode in main.js

function debugRenderer(moduleName, parentNode, popoutRef, view, viewIn, viewOut)
{
	return function(tagger, initialModel)
	{
		var appEventNode = { tagger: tagger, parent: undefined };
		var eventNode = { tagger: tagger, parent: undefined };

		// make normal stepper
		var appVirtualNode = view(initialModel);
		var appNode = render(appVirtualNode, appEventNode);
		parentNode.appendChild(appNode);
		var appStepper = makeStepper(appNode, view, appVirtualNode, appEventNode);

		// make overlay stepper
		var overVirtualNode = viewIn(initialModel)._1;
		var overNode = render(overVirtualNode, eventNode);
		parentNode.appendChild(overNode);
		var wrappedViewIn = wrapViewIn(appEventNode, overNode, viewIn);
		var overStepper = makeStepper(overNode, wrappedViewIn, overVirtualNode, eventNode);

		// make debugger stepper
		var debugStepper = makeDebugStepper(initialModel, viewOut, eventNode, parentNode, moduleName, popoutRef);

		return function stepper(model)
		{
			appStepper(model);
			overStepper(model);
			debugStepper(model);
		}
	};
}

It looks like tagger has an undefined parent.
Does anyone know what the problem might be?

assuming no longer an issue? i'd reclone and reinstall latest, make sure you are on Node 6+

I have the same issue "Uncaught TypeError: Cannot read property 'appendChild' of null at bundle.js:17580"

Using node v8.9.1
