Up to now, we haven't been accounting for `#url` symbol arguments in `livecheck` blocks that don't reference a checkable URL. This can either be an invalid symbol (e.g., using the `:stable` formula symbol in a cask) or a valid symbol where the referenced URL doesn't exist (e.g., using `:head` when there's no `head` URL). [Almost all of the valid symbols are required URLs but `head` is optional.] Over the years, we've had a handful of slips where we've used `:url` in formulae (when it's only valid in casks) and `:stable` in casks (when it's only valid in formulae). In this scenario, `livecheck_url_string` is `nil`, so livecheck falls back to `#checkable_urls`. In this scenario, `stable` and `url` are the first checkable URLs for formulae and casks (respectively), so the checks ended up working as expected merely by chance. This isn't obvious in the output and even the debug output looks normal. It only becomes apparent that livecheck isn't working as expected if it iterates through more than one checkable URL before reaching one that works (not the case in those instances). With that in mind, this adds an error when a `#url` symbol is used but it doesn't correspond to a checkable URL. This will account for both of the mentioned scenarios (invalid symbols and valid ones referencing a non-existent URL) and prevent livecheck from quietly proceeding in an unexpected manner.

Contributing
We'd love you to contribute to Homebrew. First, please read our Contribution Guide and Code of Conduct.
We explicitly welcome contributions from people who have never contributed to open-source before: we were all beginners once! We can help build on a partially working pull request with the aim of getting it merged. We are also actively seeking to diversify our contributors and especially welcome contributions from women from all backgrounds and people of colour.
A good starting point for contributing is to first tap homebrew/core, then run brew audit --strict with some of the packages you use (e.g. brew audit --strict wget if you use wget) and read through the warnings. Try to fix them until brew audit --strict shows no results and submit a pull request. If no formulae you use have warnings you can run brew audit --strict without arguments to have it run on all packages and pick one.
Alternatively, for something more substantial, check out one of the issues labelled help wanted in Homebrew/brew or Homebrew/homebrew-core.
Good luck!
