Google Data Studio Community Connector Error Cannot read property "status" from undefined e183a040

I'm trying to use the Google Data Studio Community Connector to pull data back from a JSON API, but when I try to set up the Connector in Data Sources and hit the "Connect" button, I get an error:

Community Connector Error

There was an error caused by the community connector. Please report the issue to the provider of this community connector if this issue persists.

Connector details

Failed to get schema: Cannot read property "status" from undefined.

Error ID: e183a040

Does anyone know if the connector is broken or am I doing something wrong???
