Unable to determine the data source due to unknown functions.

I'm using the Github Custom Connector for Blackbaud RE, and I'm trying to setup my dataset in PowerBi Service for scheduled refresh using the personal gateway. When I go to the dataset settings, I get the following error message:
"Unable to determine the data source due to unknown functions. When custom connectors are used, the error can happen if gateway doesn't have the extension enabled. Details: Query contains unknown function name: Blackbaud.Contents.
Data source for Query1"

and below that is a hyperlink for "Discover Data Sources" but it doesn't seem to fix anything.

In my Personal Gateway settings I have signed in, and under "Connectors" I see the Blackbaud connector loaded.

What could the problem be?

A couple of things you might want to check:

Gateway Service Account that services the gateway is signed in to a user that can access your local device and not using the default Service Account.

Setting the Privacy Level in the PBI Services to Organizational.
