Price and other information is missing in products association for bundles

[r4pt0s]

I followed along the video tutorial and everything worked until adding the cards to the bundle tab.

As soon I set that up, I got a error 500 with the message, that calculatedPrice is not allowed to be null.

I checked it with a dump in the twig file instead of rendering the box-standard component and the calculatedPrice property is indeed null for all products which I added to the bundle.

I also tried to use the entire sample code from github and got the exact same result.

The interesting thing is, that I got the price information and the cover as well

I also made sure to use products which don't have any specifc price setups in the background if that might be an issue.

I use the docker dev environment with shopware version 6.4.99 with demo-data.
Any chance that there happened something in shopware version 6.4.99?
