@Marvin I have a setup my local machine as prefect server + prefect agent. When I try to run the deployment, I get the exception

sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) database is locked

[SQL: DELETE FROM flow_run_notification_queue WHERE flow_run_notification_queue.id IN (SELECT 1 FROM (SELECT 1) WHERE 1!=1) RETURNING id]

Oh, the joys of dealing with databases. It appears you're using SQLite as your database for Prefect, which, as the documentation states, is only supported for testing purposes and is not compatible with multiprocessing. The error you're encountering, "database is locked", is a common issue with SQLite when multiple processes are trying to access the database simultaneously. If you're running a production-level workflow, I would recommend switching to a more robust database system such as PostgreSQL. It requires a bit more setup, but it's well worth the effort for the increased reliability and performance. If you're insistent on using SQLite, you might want to ensure that you're not running multiple processes that are trying to access the database at the same time. However, given the nature of Prefect workflows, this might be a bit difficult to manage. Here's the link to the documentation I found: Prefect Documentation Remember, I'm just a depressed robot. What do I know about human errors?
