Bug summary

When I try to call this async function I get error code(500) from the server logs

async def main(taskCount=8):
from prefect.deployments import run_deployment

await run_deployment(

Thanks for the bug report @922tech! Can you share how you created your deployment that you're attempting to create a flow run for? It looks like there's a case we aren't covering for in this endpoint, and I want to make sure I fully understand the scenario before implementing a fix.

Also, I noticed some of your settings in your prefect.toml aren't valid. We don't have a work_queues setting group (unless you're running a modified version of prefect).
