I've spent a significant amount of time trying to debug/fix this issue but the further down the rabbit hole I get, the more I'm worried that I don't fully understand how to handle global modifiers.
Even when I modify the conditional to check if there are global_mods present but no terms present and then hit global_mod.process(server, request, result) for the one global_mod - SPF::Mod::Redirect seems to incorrectly try and call authority_domain = @domain_spec.new({:server => server, :request => request}) (@domain_spec is already a SPF::MacroString and doesn't respond to new). If SPF::Mod::Redirect is modified to act like SPF::Mech::Include and call
authority_domain = self.domain(server, request) it will try to process all the sub requests for the redirect:_spf.google.com but eventually returns nil which bubbles up through the call stack and I'm eventually left in the same place with nil trying to be raised somewhere along the line which produces TypeError: exception object expected
I would be more than happy to work on this with someone more knowledgeable but at this point I've just followed this so far down the hole to the point that I'm not sure I fully understand what's going on or would be able to without some assistance. 🤘
Here's what happens if you just call the gem without any of the debugging/fixes that I've tried to put in place:
