Error invoking WSDL service based activity

Hi Community,

I’m having a problem while trying to create a library with WSDL based service.

I’m trying to access public SOAP API at:

Definition: (6.6 KB)

The simple http request works fine.

No authentication required. SoapUi works fine also.

When creating a service based on a wsdl definition everything looks ok.
I’m creating a “request” object with appropriate data but when inovoking the service activity it returns

“Could not invoke client method.” error.

Is there something wrong with the built request?

Please find a sample project which shows the working http request with sample body soap envelope, and steps to call the created service. (34.2 KB)
