        prefect_flow = Flow(name="random_flow", fn=random_fn)
        deployment = Deployment.build_from_flow(

I'm trying to build a deployment for a flow that is created dynamically. While the deployment 'random_flow' gets created successfully, when I try to run the same, I get this error.

Flow could not be retrieved from deployment.

What can be done to link this flow to the deployment properly and get it to run through the Orion UI?

I didn’t have an issue deploying with above code, provided I modified it like so

from prefect import flow
from prefect.deployments import Deployment

@flow
def random_flow():
   print("Random")

@flow
def main_flow():
        deployment = Deployment.build_from_flow(
            flow=random_flow,
            name="random_deploy",
            version=1,
            work_queue_name="test-queue",
        )
        deployment.apply()

main_flow()
