Additional Context

Looking at recent commits, found THIS one and I guess the problem is related to the cacheWillUpdate change. Maybe because of using Optional Chaining.

Hello, i have the same problem in node.js v.12. It does not support optional chaining. v5.2.1 works good.

Version 5.2.7 should fix this problem.
