'System.ServiceModel.FaultException' error

Posted on by Sridhar Narayanan 1,027

Hi Experts,

I created a custom service in D365 and tried accessing the service from a C# console application.

Build is successful in the console application; however, when I run the application, system is throwing below error

An unhandled exception of type 'System.ServiceModel.FaultException' occurred in mscorlib.dll

Any pointer would help.

Thanks,

N.Sridhar

    It means that your service operation threw an exception and you can't fix it if you don't know what exception is it. You could debug your service, but your first step should be looking at details included in the fault exception.

    Hi Martin,

    Below are the details of the fault error exception.

    {"There was no endpoint listening at https://xxxxx.cloudax.dynamics.com/.../xxServiceGroup

    that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details."}

    {"The remote server returned an error: (407) Proxy Authentication Required."}

    Thanks,

    N.Sridhar

    Did you try samples from Microsoft? If they work but your SOAP service doesn't, you have a problem with that particular services. If samples don't work either, you have a problem with configuration. The latter message suggests that there is a problem in authentication, but you didn't tell anything about what you did, so I can't comment on it yet.

    Thanks Martin. Earlier I didn't provide authentication details to access the service.

    Martin,

    What do you mean by samples?

    I mean the GitHub projects with sample solutions from Microsoft: github.com/.../ServiceSamples
