[BUG] anywidget.js 404 Not Found when rendering Altair charts

[jeeenolee93-byte]

There was an issue where the UI displayed using the render_altair decorator wasn't fully displayed. The related log was as follows:

INFO: 127.0.0.1:57398 - "GET /app_dir/anywidget.js HTTP/1.1" 404 Not Found

Altair rendering appears to be unavailable on the official Shiny for Python website.

Is there a problem with reading the js file on the Altair server side, or is it a Shiny for Python issue?

Is this a Shiny for Python issue? If so, please fix the bug.
