Describe the Bug

It should build and deploy to CloudFlare but it keeps erring saying WeakRef is not supported.
But WeakRef is being used by discord.js dependency in node_modules so there isn't anything I can do.
What's a work around?

I'll mark this as a feature request. Workers intentionally disables use of WeakRef and FinalizationRegistry in order to limit observability of GC, and the nondeterminism it brings, for a number of reasons. I believe WeakRef would likely be somewhat safer to enable than FinalizationRegistry but they are used so frequently together that it might actually cause more issues to enable one but not the other. We'll need to carefully consider this.

Hi, same issue when using elasticsearch.js

Any quick solution for now?
