Blank page and MIME type error when running SampleApp with ReactPy on Python 3.10.5 and Windows 10

[sn0vv]

Hello,

I install reactpy on Python 3.10.5 and Windows 10.

pip install "reactpy[starlette]"

I run the sample application.

python -c "import reactpy; reactpy.run(reactpy.sample.SampleApp)"

But Chrome shows a blank page and DevTools Console outputs the following:

index.a1f87a11.js:1 Failed to load module script: Expected a JavaScript module script but the server responded with a MIME type of "text/plain". Strict MIME type checking is enforced for module scripts per HTML spec.

Visual Studio Code TERMINAL outputs the following:

(venv_react) PS D:\dev\python\reactpy\venv_react> python -c "import reactpy; reactpy.run(reactpy.sample.SampleApp)"
