Hey guys, I've upgraded from prefect orion

2.0a9

to

2.0a12

. When I try run the server

prefect orion start

it throws this error:

sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) table flow already exists

how do I get around this?

Try:

prefect orion database reset

This page explains it more: https://orion-docs.prefect.io/getting-started/installation/#upgrading-the-database

"Resetting the database with the CLI command 

prefect orion database reset

 is not compatible a database from 2.0a9 or earlier. Instead, delete the database file 

~/.prefect/orion.db

" Deleting the database manually worked
