Description
Running a shiny express app with this code
with layout.page_sidebar():
with layout.sidebar():
"sidebar-content"
throws an error in the console - TypeError: page_sidebar() missing 1 required positional argument: 'sidebar'
Ideally, we should let users know to use page functions with layout.set_page instead of with

Research direction
Start by reproducing the shown page_sidebar() and sidebar() nesting in a Shiny for Python express app. Then inspect the page functions and layout.set_page API to determine where the misleading TypeError can be replaced with guidance; done means users are directed to use page functions with layout.set_page instead of with.
