Undefined options.targetBuffer in cornerstoneWADOImageLoader

[sefranz]

Hello there,
I am trying to build a very basic custom viewer using @ohif/core and @ohif/extension-cornerstone.
When loading a series I get an exception within the cornerstoneWADOImageLoader:

Unhandled Runtime Error
TypeError: f is undefined
Call Stack
./node_modules/cornerstone-wado-image-loader/dist/cornerstoneWADOImageLoader.min.js

The error traces into the createImage function called by cornerstone. As implemented in the @ohif/viewer this method is called without the options function parameter and therefore the error occurs.

Nevertheless, in the demo version of the viewer this error obviously does not occur and I would like to know what I am missing in my implementation.

I built a minimal version of a viewer here: ohif-nextjs-minimal
that should load one single series from a study and display it in using react and cornerstone.
Can you tell me what I am missing here?
