Functions as layout no longer work (_validate_layout throws error)
See original GitHub issueHello,
since the _validate_layout method was introduces in dash.py setting functions as layout no longer works, because calling traverse() on an function fails.
Setting a function as layout is necessary to make the app reload the layout on page reload as described in the documentation.
Currently the fastest option is to remove the _validate_layout call in the _setup_server method.

Will have a fix for this soon, this was introduced in 0.22.0 via https://github.com/plotly/dash/pull/294 so you can downgrade to 0.21.1 for now or edit as above.
Checking if the layout is a function and then calling it once to validated the returned layout would be an appropriate fix.
