7 months ago seems this is because a PR introduced ?? syntax which breaks node compatibility
what version of node do you use?
you can prove that's the case by using a newer node version temporarily and seeing if the error stops happening.
if that is the case, we may need to revert the syntax

Problem First noticed this problem during a nightly build, at 2024-01-07T00:28:35.648Z (shortly after 4.4.0 was last published) and nightly thereafter:

Reverting to version 4.3.10 resolved the issue.
