Has anyone used the "Export CDT To Excel" document generation smart se

Has anyone used the "Export CDT To Excel" document generation smart service. I can't find any information in the Appian documentation and I am having problems with the configuration I believe. I am getting an error "There is a problem with task “Export CDT To Excel” in the process “exportTest”
Problem: An error occurred in executing an Activity Class.
Details:
Recommended Action: Examine the activity class to correct the error and then resume.
Priority of this problem: High Priority"

Any ideas would be greatly appreciated.
