Uncaught DOMException: Failed to execute 'importScripts' on 'WorkerGlobalScope'

I write a simple app and try to publish to gh-pages. When I visit the published url, I got the following errors on the console of dev-tools.

:1  Uncaught DOMException: Failed to execute 'importScripts' on 'WorkerGlobalScope': The script at 'https://cdn.jsdelivr.net/pyodide/v0.23.0/full/pyodide.js' failed to load.

I tried flet run main.py -w which is working. I also tested locally via serve the dist of flet publish, the same problems.

I tried again, the error disappeared, it's so strange,

Maybe the content-type of https://cdn.jsdelivr.net/pyodide/v0.23.0/full/pyodide.js is wrong when execute importScripts("https://cdn.jsdelivr.net/pyodide/v0.23.0/full/pyodide.js"); in the worker sometimes, see https://developer.mozilla.org/en-US/docs/Web/API/WorkerGlobalScope/importScripts#exceptions.

Finally, I found the problem is my network issue when visit https://cdn.jsdelivr.net/, now I use self-hosted pyodide instead.
