Hi! Will this run on MacOS Monterey?

I'm currently looking to implement something like this, but while this seems to work perfect on Catalina I'm not sure it does on Monterey (the dry run doesn't yield a list of excluded paths).

I really would love to find a (semi) automated way to exclude node_modules and .venv folders from my Time Machine backups.
