Filtering a data type on a list of dates based on date_input_start date_input_end

Hello, I am having an issue in filtering a data type products which contain a list of unavailable dates (list_unavailable_dates).

I’m trying to only show the products that are available, in a repeating group, and exclude the products where list_unavailable_dates doesn’t contain the date range between date_input_start and date_input_end.

The expression that makes sense to me stays incorrect. Has someone managed to tackle this issue?

I have gone through all the related Date topics but none solves my problem.


I’m not sure if anyone had the chance to see this post. However I’ve been struggling quite a bit with this issue and I still can’t find a solution. Anyone could give me a hint?
