Implementing Auto-Refresh on a Custom Data Connector

Hi,

I'm attempting to see if it's possible to implement Auto-Refresh functionality in a custom data connector. I've written one that works fine - but when people attempt to turn on Auto-Refresh they get an error message like:

You can’t schedule refresh for this dataset because the following data sources currently don’t support refresh:
Data source for Prod_Feedback
Data source for Prod_User
Discover Data Sources
Query contains unknown function name: Neo4j.ExecuteCypher.

Is there anything I (as the connector developer) can do to resolve this? 

thanks!
