@villebro can you spin up an ephemeral?

[villebro]

/testenv up

[github-actions]

@villebro Ephemeral environment spinning up at http://35.164.94.117:8080. Credentials are admin/admin. Please allow several minutes for bootstrapping and startup.

[villebro]

@sadpandajoe here's a bubble chart created from scratch: http://35.164.94.117:8080/superset/explore/p/BzZjq7RQNnK/

LGTM

[sadpandajoe]

LGTM too. Tested out on new bubble chart along with playing around with the truncate feature on there.

Ephemeral environment shutdown and build artifacts deleted.
