Bundles Building /@@resourceregistry-controlpanel in Plone 5.2

Seems like building bundles is broken (again) in Plone 5.2
For me, the building just 'keeps on forever'
Probably due to a javascript error: TypeError: undefined is not an object (evaluating 't.window.requirejs.optimize')

Can anyone confirm this?


Can I rebuild from the command line ?

Espen, you know you need to provide more detail... Is this on Python 2 or 3? What is in the bundle? What is in your browser console? (the full error stack)

This might help?

https://docs.plone.org/adapt-and-extend/theming/resourceregistry.html#compiling-bundles

or there is this theming training:

https://training.plone.org/5/theming/theme-package-7.html

I don't have access to that site at the moment, but there was just one javascript error:

 TypeError: undefined is not an object (evaluating 't.window.requirejs.optimize')

Usually, an error like this is when a requirement is missing (?)

How do I get more 'error stack'?

Edit: We are talking about the default Plone bundles… a fresh Plone, without any extra add-ons installed.
