The pyscript_component has its initial kwarg set to "" by default, but this case fails

[shawncrawley]

The actual root of this issue is caused by the underlying call to reactpy.utils.string_to_reactpy, which will fail if called with an empty string.
This was discovered in the context of refactoring reactpy-django to work with the latest reactpy core pre-release. The reactpy-django package had its own implementation of pyscript_component, but in switching that one out for the one officially provided by reactpy core this issue was revealed.

See the code here:

reactpy/src/reactpy/executors/pyscript/components.py

Line 42 in 8c6732c

initial: str | VdomDict | Component = "",

Reproduce on reactpy-2.0.0b9 with:

from reactpy.utils import string_to_reactpy
string_to_reactpy("")
