Soap fault : ErrorMsg: Unable to find a matching Operation for this remote invocation null.

Soap fault occurred while invoking the web service. ErrorMsg: Unable to find a matching Operation for this remote invocation null. Please check your operation name.

I got this error while invoking a connector.

What I did was : Ideally it was a get operation, hence there shouldn’t have been an input. But, there was an input, hence I just hard coded the input with blankspace.

Thanks
