Overrided Soap Fault Exception

[guhkun13]

I was receiving SOAP Fault Exception with http status code 500 with error message but the error was override by code, if the http status code != 200 or http status code >= 400, with *gosoap response is nil and new error.
So the error message not showing properly to the client (not showing the 'original response' from server)

I have exactly the same issue, SOAP API returns 500 with error message, but I can't read it
