It seems that #38867 made `AppProps` always require the `pageProps` object shape to be passed as a generic since the default `{}` will throw a TS error if you try accessing any property: Before:  After:  Technically, it would be more correct since accessing `pageProps` properties would otherwise be unsafe, but this seems to break the current behavior. ## Bug - [ ] Related issues linked using `fixes #number` - [ ] Integration tests added - [ ] Errors have a helpful link attached, see `contributing.md` ## Feature - [ ] Implements an existing feature request or RFC.
