Postman web service Error - Unable to connect to external workflow tool

[PriteshJadhav]

Hi, We are trying to connect to external workflow tool through the exposed BP web service. Trying to test the connection using Postman and get the following error below, we get the same error through the connection with workflow tool. The request works through SOAPUI though. Request -                      1234           Error Response -                          Couldn't process soap inputs - System.NullReferenceException: Object reference not set to an instance of an object.    at BluePrism.AutomateProcessCore.clsProcessWSDL.ProcessSOAPInputs(String sInputs, clsProcess proc, String& sMethod, String& sSession, String& sErr)             Anyone faced this issue? Anything that I am missing here? Appreciate the help

Is your Workflow Tool within the same network where your Blue Prism is? If they are not in same network, you need to work with your infra/network team about firewall, etc. My hunch is that your SOAPUI is installed locally in your machine and in the same network with BP that's why it works. You can try downloading Postman locally and try, it should also work.

Hi Greg - Thanks for your response. Both SoapUI and Postman are installed locally and BP and workflow tool are in the same network. Is it the way Postman is sending the request is different from SoapUI in some way? The workflow tool is facing the same error as Postman and somehow SoapUI gets it to work. Any thoughts on why this discrepancy?
