I tried to run the same app on an ubuntu machine with the same versions of npm yarn and node, and it works, but not on this one.

@hecomp there’s no instructions you can follow to resolve this currently. Please wait for npm to purge or update their edge caches!

---

To clarify, there is nothing we can do to fix this. Please be patient, it will resolve in time.

Once it’s resolved, you’ll need to deeply upgrade dependencies by running yarn upgrade.

If you use npm, you may need to delete package-lock.json and re-run npm install to fix it.

I’ve just created a new project and it seems to work as intended now.

Edit:

Made it work in an existing project by running these steps:

1. Delete node modules
2. Delete package-lock.json
3. npm i
