I have the following return and I want to infer the types of a single item, before I added the include bit the code worked, but now it gives me an error, how to set it up correctly?

Prisma won't properly infer types with a condition in select input You better create a separate prisma findMany for each group type

I thought this might be the problem but even if I just have a price: true the error is the same, I dont need it to tell me what pricing is there, I just dont want it sent to the user, it pretty much just have every price as number | undefined which is fine by me the issue is that I need to turn it to a singular item from the array and its not working when having that include, with or without the coditions

Does this help? Prisma has some tools to infer the types of select, include, etc..., I also had a similar use case. Sorry, forgot to address the conditionals. I found a bug report here
