vpulim/node-soap

Hi all, I upgraded from v 0.37.0 to 0.40.0 and I noticed a change in how errors are returned.
I'm using a WSDL instance and the same request with 0.37.0 returns an error like this:

{
   "root":{
      "Envelope":{
         "Body":{
            "Fault":{
               "faultcode":"soap:Server",
               "faultstring":"Il codice fiscale non e' nel formato corretto di 16 caratteri",
               "detail":{
                  "WSException":{
                     "error":"3",
                     "message":"Il codice fiscale non e' nel formato corretto di 16 caratteri"
                  }
               }
            }
         }
      }
   }
}

With 0.40.0 I get this (I replaced some informations with ...):

{
   "message":"Request failed with status code 500",
   "name":"Error",
   "stack":"Error: Request failed with status code 500\n at createError (/usr/local/src/liveid/api/node_modules/axios/lib/core/createError.js:16:15)\n at settle (/usr/local/src/liveid/api/node_modules/axios/lib/core/settle.js:17:12)\n at IncomingMessage.handleStreamEnd (/usr/local/src/liveid/api/node_modules/axios/lib/adapters/http.js:260:11)\n at IncomingMessage.emit (events.js:326:22)\n at IncomingMessage.EventEmitter.emit (domain.js:483:12)\n at endReadableNT (_stream_readable.js:1241:12)\n at /usr/local/src/liveid/api/node_modules/async-listener/glue.js:188:31\n at processTicksAndRejections (internal/process/task_queues.js:84:21)",

      "headers":{
         "Accept":"text/html,application/xhtml+xml,application/xml,text/xml;q=0.9,*/*;q=0.8",
         "Content-Type":"text/xml; charset=utf-8",
         "User-Agent":"node-soap/0.40.0",
         "Accept-Encoding":"none",
         "Accept-Charset":"utf-8",
         "Connection":"close",
         "Host": ...,
         "Content-Length":1529,
         "SOAPAction":"\"\"",
         "Authorization":"Basic ..."
      },
      "transformRequest":[
         null
      ],
      "transformResponse":[
         null
      ],
      "timeout":0,
      "xsrfCookieName":"XSRF-TOKEN",
      "xsrfHeaderName":"X-XSRF-TOKEN",
      "maxContentLength":-1,
      "maxBodyLength":-1
   }
}

Does anybody have some ideas of why this happens and how to restore an error like the one I get with 0.37.0 (beside from downgrading to 0.37.0 :P)?
