Something odd with the bundle registration? AttributeError: 'dict' object has no attribute '__identifier__'

[agitator]

I already came accross this problem on Plone 5.2 and didn't use it in production then.
Now testing out the deployment on Plone 6 and get this error again when I run the migration steps for plone.staticresources.

lazysizes isn't even installed, just added to the setup.py of my integration package....
Any idea what could be the issue?

very weird; you'll have to dig deeper: collective.lazysizes don't register its resources in Plone.

I've digged into this. Turns out, that the v10 upgrade step isn't compatible with Plone 6. See https://community.plone.org/t/solved-error-while-installing-collective-z3cform-datagridfield/19801/11

I'll prepare a PR

A bit more info:

https://github.com/collective/collective.lazysizes/blob/master/src/collective/lazysizes/upgrades/v10/__init__.py#L7

This overrides the zope.deferredimport marked interface and breaks all Products.CMFPlone.interfaces.IBundleRegistry imports.

If you change those imports to plone.base.interfaces.resources.IBundleRegistry it fixes the error above also, but there are several other places which still import from the old module.
