With recent ethereumjs/util v8.0.4, @chainsafe/ssz dep is added which shows above error. It can be specific to node.js 14

Hey @wemeetagain, do you know what is going on here? 🤔

Context is that we have now released a version of our libraries containing the @chainsafe/ssz dependency for the first time (we have this in @ethereumjs/util now to prepare for some SSZ withdrawal root functionality in the @ethereumjs/block library (which is still more or less unused, so in the worst case we could remove again for now).

So what happens here is that there is a replaceAll() call still in the library, which is ES2021 and therefore not compatible with Node 14 or many browsers. Looking at your library I see a build target of ES2019 in the package.json file (or is this the wrong one?), so I wonder why there is still a replaceAll() (from util/string.ts) in the distributed package?

Not sure if it's possible for you guys to do short-term fixing releases here, I guess otherwise we need to take the library out of our dependencies again and deactivate the released functionality (which wouldn't be such a big deal right now, since the usage of this functionality is still somewhat away. We should then exchange though if the underlying eventual build target issue can be mitigated mid-term).

As we were planning a release and this thing came out, we are exploring a tentative fix. Still, would like to have more info to fix it permanently

[holgerd77]

We are on a fix, 80-95% work guarantee (PR in the works right now). I we can confirm we would release in the next 1-2 hours.

[holgerd77]

Ok, released, could you confirm that (hopefully) things work again?

[Aniket-Engg]

Yes, everything is fine again. Thank you so much for quick fix.
