Why is my custom connector stuck on "creating dataset"

I'm having an issue when trying to test my connector. When I Run Script and have "Create/Update DataSet" checked, it finishes the "Sending Data" portion but then just stays on "Creating Dataset" without ever letting me look at it. Am I doing something wrong to cause that?





    I would need to get a better look at how you have set up the connector in order to understand why it is acting this way, can you provide some information on the configuration?
