@ngleader, do you see any errors in the Browser Console?

Are you able to create a panel with the get or smembers command and display values on your dashboard?

I will check on my test environment.

@ngleader, I remember 8.1.X had issues with loading Variables for Default Data Source, which was fixed in 8.2.X. Let me check what happened in 8.3.0.

@ngleader, I just tested on the 8.3.0 and everything is working as expected.

Please let me know if you see any issues in the Browser Console.

@ngleader It's the same issue with variables when the data source is set as Default. I just reproduced the issue on 8.3.0.

Could you please unset 'Default' and it should work as expected?

I will check the code and investigate with the Grafana team if necessary.

@ngleader Thank you for opening the issue. The bug is fixed and will be a part of the upcoming release.
Meanwhile, variables should work for the Redis data source not marked as Default.

Please let me know if there is anything else.
