Failing module

• GitHub: https://github.com/fonsp/Pluto.jl - https://github.com/fregante/many-keys-map
• npm: https://www.npmjs.com/package/many-keys-map

import ManyKeysWeakMap from "https://cdn.esm.sh/v64/[email protected]/es2021/many-keys-weakmap.js"

Error message

After onload I got this:

GET https://esm.sh/v64/[email protected]/es2021/many-keys-weakmap.js net::ERR_ABORTED 500 (Internal Server Error)

Additional info

• esm.sh version: 64
• Browser version: Latest Chrome

crossref: fonsp/Pluto.jl#3019 and fonsp/Pluto.jl#2707
context:
Pluto HTML bundles that are on the internet and refer to ESM are more-or-less immutable, as they were usually built as part of some course that has now ended, so it's not maintained.

the url should be https://esm.sh/v64/[email protected]/es2021/many-keys-weakmap.mjs now

Hey! The problem in our project is that we version-pinned the esm.sh URL to future-proof the import. So we used

import ManyKeysWeakMap from "https://cdn.esm.sh/v64/[email protected]/es2021/many-keys-weakmap.js"

with the assumption that this would work forever, by pinning the esm.sh version, the package version and the compile target.

This import is baked into some archived html files that we generated in the past, and these files suddenly stopped working. Since this was an archival project, we can't change the import.

Is it possible to make the original import (with .js) work again, for versions where this worked in the past?
