def method_logical_id
  # https://stackoverflow.com/questions/6104240/how-do-i-strip-non-alphanumeric-characters-from-a-string-and-keep-spaces
  # Add path to the logical id to allow 2 different paths to be connected to the same controller action.
  # Example:
  #
  #   root "jets/public#show"
  #   any "*catchall", to: "jets/public#show"
  #
  # Without the path in the logical id, the logical id would be ShowApiMethod for both routes and only the
  # last one would be created in the CloudFormation template.
