AssertionError when building yarn monorepo

[MasterOdin]

Example repo: https://github.com/bishopcais/io/tree/typedoc-missing-exports (note, the branch is typedoc-missing-exports).

When running yarn docs within the root of that repo, I get the error:

yarn run v1.22.10
$ typedoc
Info: Loaded plugin typedoc-plugin-missing-exports
TypeDoc exiting with unexpected error:
AssertionError [ERR_ASSERTION]: The expression evaluated to a falsy value:

  assert(parentSymbol)

This sounds like a similar error as #4, but opened a new issue as did not want to piggy back off it like I did in #3 in case they are different. Feel free to close as a duplicate though.

Wow, well tracking that one down was an adventure... This is crashing because of how Date is declared in @types/node version 12... it won't show up with @types/node v16

Shoot. That fix got the first crash, but there's another later on for presumably a similar reason.

Not really happy with the fix in bf41de3, but it works...

Thanks for the fix! It has worked great for me so far.
