Sounds to me like an issue that comes with coupling of validation with serialization. A lot of these API frameworks combine the two, with a the goal of automating validation when receiving data from clients, but then also do that validation when serializing response data, which should already be validated if it's sitting in your database. I've ran into similar issues with FastAPI and DRF when dealing with really large payloads.
