The exception doesn't get thrown or logged to the console.

I found this by setting the activeLearningJobUrl and activeLearningJobType to another docker image such as "foobar/superpixel:latest#SuperpixelClassification` here:
https://github.com/DigitalSlideArchive/wsi-superpixel-guided-labeling/blob/master/wsi_superpixel_guided_labeling/web_client/views/body/ActiveLearningView.js#L60

when I then load the active learning from DSA, I am met with an empty screen, no exceptions, no error logs:

A quick fix to make it easier to debug would be to add an console.error next to the exception.
I don't enough javascript to suggest anything else 😅
