Type instantiation error when combining parseParams and deeply nested route tree

I'm getting the

Type instantiation is excessively deep and possibly infinite. ts(2589)

Type instantiation is excessively deep and possibly infinite. ts(2589)

error, when I have a route with

parseParams

parseParams

on the top of the route tree and more than 8 nested sub routes under it. Removing

parseParams

parseParams

allows me to have more than 20 nested routes without the error.

Any ideas what might be causing it?
