I’ve noticed on occasion that the when running DAGs in the playground the Waterfall animation either doesn’t run or will run continuously even after the job has either succeeded or failed. Usually I end up waiting for the “Running” pill to change to succeeded or failed and then click over to the Run Log in the UI to inspect the run. Ultimately it’s not a huge deal because the jobs still run but the first time it happened I definitely just thought something was wrong with my job. Just curious if this is a common issue or if maybe I’ve done something in my jobs that’s causing some event to not emit to the client interface.

How is your instance set up? Is this just local or using a postgres DB? What OS are you using? The live view is powered by a GraphQL subscription over websockets from the client to the web server, then the web server is watching the database for changes. In sqlite its watching for file modifications to the db file, and for postgres we use listen/notify.

This is just happening locally I’m using Docker to host a local PostgresDB, I’m on MacOS
I’ve sort of followed along with this particular setup example https://github.com/dagster-io/dagster/tree/master/examples/deploy_docker

interesting - and to clarify you see it work sometimes but inconsistently? or does it always not work right?
