End Point Reference (EPR) not found error

Hello guyz,

I consumed a third party WSDL and inside that there are three connectors. To invoke two connectors no input is required and when i invoke it, i receive an error saying that “EPR not found”.

If i map a document and pass a string as an input i receive a response back. Even though the input that i am sending is being ignored on the backend, i am receiving a proper response back.

Is anyone able to invoke a WSD connector with out inputs in 8.x IS?
