Airflow web-server raises a werkzeug.routing.BuildError

Astro CLI

After cleaning up every airflow-related docker stuff (images, volumes etc) and starting airflow locally using the astro cli, I’m getting the following error:

Hi @sp1thas

Running astrocloud dev kill and then astrocloud dev start again should take care of this. Note that this will purge any variables, connections, metadata etc that were stored in the local postgres instance.

Alternatively if you’d like to avoid using kill, you can try TRUNCATE dag table locally and that should resolve as well.

This worked for me as well for local deploys! $ astro dev kill and $ astro dev start
