This was an error introduced in https://github.com/babel/babel/pull/10171/files.
The helper got the keys from
source, which was defined at the previous iteration.Also, I added a test faking an old env by deleting
Object.getOwnPropertyDescriptors😎If I had used
letthis would not have happened. Also, this is what happens when I merge a PR without waiting for the usual two ✔️; this bug could have been caught by more eyes looking at it.@JordanProtin Could you check that if you update
_objectSpread2like this in@babel/helpers,@babel/runtime,@babel/runtime-corejs2and/or@babel/runtime-corejs3in yournode_modules(there could be multiple copied of each package) it works? I can reproduce the error without this fix but it seems to be fixed.
