Could you please run

prefect flow-run ls

and let us know whether you can see the state of each flow run in the CLI?

What’s the output of that on your server hosting the API? Is your API the same version? Are you using SQLite or Postgres?

Tuoyi Zhao

the API is hosted locally....i use the default the backend database, should be SQLite in this case

@Tuoyi Zhao, we believe that this issue was cause by a database migration error in the 2.7.5 release impacting SQLite users. We'll share more information as soon as possible.

I just ran a simple test to print current time.....I can see the pending tag in Deployment and Flow Runs, but that pending task is hanged and will not be executed. I checked the agent, and it shows:

i can run this flow successfully if run directly without deploy it first.....was the deployment from python changed in the new version?
