Prefect Community

Hello everyone. I am using prefect server and local agent to setup. The prefect agent keeps throwing `ERROR - agent | Failed to query for ready flow runs`, even though I am able to run the flows.

Traceback of the error
```Traceback (most recent call last):

It looks like a version mismatch issue. Make sure that your Server has a Prefect version which is &gt;= the Prefect version used in the registration environment and on your agent.

Hi <@U02H1A95XDW>  I am running `0.15.10` in both the places ie server and registration/agent env.

Can you reregister and see if this fixed the issue? How did you register this flow - did you use the prefect register CLI? I would recommend registering with the CLI.

Also, did you explicitly define storage and run config?

I tried with reregister, but the issue didn't go away. I am not using the CLI as I am trying to register through code using flow.register().

No, as I am using local run, didn't explicitly define storage and run config. I will do that and see if anything changes.
