@ribizli,

I downloaded your workflows and ran them. The widgets run fine on my end:

I suspect it may be related to an issue mentioned in this thread:

It affects all node views and those node dialogs that have a node view preview; but ‘only’ in case the Analytics Platform has been directly started with the Classic UI (it remembers the UI it has been shutdown with). We will publish a fix as soon as possible. Till then you either use the Modern UI (it is not an issue there) or switch to the Modern UI and back again to make it work in the Classic UI, too.

I would try as the thread says and switch between 2 UI’s and see if that fixes it.
