errors.rb

An HTTP request has been made that VCR does not know how to handle:
        GET https://api.mailgun.net/v3/address/private/validate?address=eng@foobar.com
      
      There is currently no cassette in use. There are a few ways
      you can configure VCR to handle this request:
      
        * If you're surprised VCR is raising this error
          and want insight about how VCR attempted to handle the request,
          you can use the debug_logger configuration option to log more details [1].
        * If you want VCR to record this request and play it back during future test
          runs, you should wrap your test (or this portion of your test) in a
          `VCR.use_cassette` block [2].
        * If you only want VCR to handle requests made while a cassette is in use,
          configure `allow_http_connections_when_no_cassette = true`. VCR will
          ignore this request since it is made when there is no cassette [3].
        * If you want VCR to ignore this request (and others like it), you can
          set an `ignore_request` callback [4].
