to make use of did_you_mean gem. The did_you_mean gem only supports NameError, NoMethodError and KeyError. However, for NameError the message does also need to match a certain format and we can not use a custom message like 'Factory not registered ...'. Therefore using KeyError is to only logical conclusion. The did_you_mean gem makes use of the receiver attributes, but in Ruby > 2.5 it is not possible to set the receiver and key attributes on a KeyError (they are only set when the KeyError is raised in C). We explored monkey patching KeyError for earlier versions of Ruby, but it was a problematic solution. Instead we can rescue the original KeyError, take the message from it, which will already include the did_you_mean message, then customize the message and re-raise a new KeyError with that customized message. Starting in Ruby 2.6 this will not be necessary anymore https://bugs.ruby-lang.org/issues/14313, so maybe we can get rid of it for FactoryBot 6 or 7.
