The issue is that this sort of validation boilerplate shouldn't have to be written. The framework should be able to figure it out from the HTTP handler declaration. I suspect this is why FastAPI got so popular in the Python world.

IMO, a lot of the JS world seems mentally fixated on express.js-levels of abstraction still. Anything more is viewed as "magic" and viewed as suspect because it requires learning.

The irony is that the "learning" just gets applied elsewhere; there are certain foundational building blocks that I think every language and platform needs once you start building "serious" applications.
