Thanks @sipsma! 🙏🏻

Gonna work with @dolanor on that!

The engine tests were failing due to this (private discussion). We addressed the root cause and re-ran the failing tests.

When the Node.js tests are passing, this is good to merge @jlongtine. cc @dolanor @slumbering

#4247 has been merged (thanks @TomChv )
I tried locally by rebasing this one on top of the #4247, and it worked.
So you can just rebase and merge when you want @jlongtine
