Failed to load module script: The server responded with a non-JavaScript MIME type of "application/octet-stream".

[Relaxe111]

I have started a fresh sca-react-ts just added antd. and in the snowpack.config.js set packageOptions:{source: 'remote',types:true}
I get following error:
Failed to load module script: The server responded with a non-JavaScript MIME type of "application/octet-stream". Strict MIME type checking is enforced for module scripts per HTML spec
url is:
http://localhost:8081/_snowpack/pkg/error/build:antd@v4.10.2-brvSpWOme5M2tl48XtzZ
minimal project example to reproduce error can be found: https://github.com/Relaxe111/snowpack3-csa-react-ts-antd-source-remote.git

I've noticed that similar issues appear to few packages which i use in my projects when I use source: 'remote'.

Thanks for filing. Just added a quick shortcut fix here: 76dca31

That should work until we can add some longer-term, skypack-specific contenttype handling.

I think I got the same error but it looks like the prefetch package returns text/html. Kind of strange.

similar si tuation for me to: Loading module from “http://localhost” was blocked because of a disallowed MIME type (“text/html”)
