Goal: My goal is to export the all the dashboards from the superset so that I can save them as backup and also make sure that I can import them.
Existing setup: I am cloning superset from git and using docker-compose -f docker-compose-non-dev.yml up
to setup and run the superset (following this documentation)
Issue:
Using superset CLI: I am using this documentation
to connect to the existing docker image on which superset is running and then running superset export-dashboards but it throws the following error:
