Can use live loader with the free hosted database?

I’m just getting started with Dgraph and working with the free hosted account on Dgraph cloud. I have a schema and now I want to load some test data to work with. Ideally I would like to load from a single file so it can be repeated in an automated to setup new test environments.

I am trying to use the dgraph live command but I’m having trouble connecting. Is this something that can be used with the free cloud account? I did find my “gRPC Endpoint” in the settings and I’m using that as the --alpha argument. I also generated an api key and tried passing that as the --auth_token arg. Here’s what I get:

❯ dgraph live --files dev-data.json --alpha --auth_token XXXXXXXXX

Running transaction with dgraph endpoint:

Can anyone offer advice to get me started?

Thank you!
