Resolution

1. Navigate to the Drawloop Admin tab > Settings and ensure that Connected Apps is enabled
2. If Connected Apps is enabled, confirm that the report in question exists and that the user running the Document Package/DDP has access to the folder where the report lives.
3. Make sure that the Session ID is updated in the VF page
4. Enable "Remove Invalid Characters" - this is a hidden field so you may need to edit the page layout to see this field
5. If they do not have Connected Apps, check to see if the sessionID parameter is set in the button
6. Running the package in a classic interface even tho the user is in Lightning
7. If this is occurring for an outbound message, the Drawloop Next field will need to have the userID and sandbox parameter
