BUG: node-fetch/https.get doesn't work (Socket hang up) about webcontainer-core HOT 4 CLOSED

You can unblock yourself by installing for example this Chrome extension: https://chrome.google.com/webstore/detail/allow-cors-access-control/lhobafahddgcelffkeicbaginigeejlf?hl=en

from webcontainer-core.

This is probably caused by the browser rejecting the request because of CORS reasons. From the linked Blitz above, https://stackblitz.com/edit/node-zfkjjc?file=index.js, I get this in my console before the hangup message comes:

Access to fetch at 'https://sampson.codes/' from origin 'https://node-zfkjjc.jw.staticblitz.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

Something very similar happens in our Node ORM Prisma, which needs to download a binary from a server to work: prisma/prisma#7185

from webcontainer-core.

This is supposed to work. Bug confirmed.

Thanks for reporting 🙏

Like @janpio said, this issue happens cause it's not possible to call the url from the browser's env, which is where WebContainer is running.

See an example here: https://stackblitz.com/edit/typescript-ive2dd.

You need to make sure this call works, and then the v2 project should also work.
