data-provider.js fails during container preparation (downloading, preparing).
This causes a complete halt of the visualization in the event you have a restart:always container failing on preparing (e.g. 'Invalid mount type..', etc)
data-provider.js:85 Uncaught (in promise) TypeError: Cannot read property 'ContainerID' of undefined

Not sure why, as it should've had a container ID to get that far.
