Hi,
After upgrading from 9.3.10 (first to 11, then to 12 - both have the problem) I get this error when using the function "Edit products".

Have tried this on both standard Rapido beta 2 and a custom solution currently live (I can't downgrade to 9.3.10, due to antoher issue fixed in 9.3.11).
Kind regards
