ERROR: "Test request does not exist" when using Intelligent Document Processing to send a request from Workflow Designer's Web Service activity

Behavior:
When testing a call using Natif.AI's web service, the following error message is shown;

 "Test request does not exist."

Solution:
This error may occur when the PDF file is absent; therefore, it is unable to send the test request to Natif.AI. Please refer to the following guide to solve this behavior;

1. Browse to %appdata%\DocuWare\Workflow Designer\OpenApi
2. Take the PDF file you will use for training in Natif.AI, then drop it in this location. 
3. Rename the file to testrequest so it is displayed as "testrequest.pdf"
   

Once completed, send the request again from the Web Service activity, which should now proceed without error.
