Generated types from Prisma client are not getting assigned automatically.

I'm currently following the create-T3-app tutorial with some small twists on my end (I use NextAuth and Postgres instead of clerk/MySQL, but I don't see how it would relate to this). For some reason, my types (which are correctly generated by Prisma) are not getting assigned to the Post(s) I load from my DB. (see pictures, lighter background is Theo and darker background is me) Any idea what could be causing this ?
