Node.js v20.11.0

markdown-link-check version

3.12.0 (this does not happen on any earlier versions). The same happens on 3.12.1

Node.js version

v18.12.1 (the same happens on v20.11.0)

OS

Ubuntu 20.04.6 LTS

Notes

This may have a similar root cause to #304, although the symptoms seem different.

The same happens on 3.12.1

Is it the same error on 3.12.1?

This line of code if (program.opts().ignore.some((ignorePath) => resolved.includes(ignorePath))) {
does not exists anymore in 3.12.1.

[TylerJang27]

My mistake. This is in fact fixed in 3.12.1. I was relying on my script that I thought had run on 3.12.1, but turns out it missed the release.
