Hey everyone, I’m trying to start prefect flow runs through the REST API of a self hosted prefect server version 2.8.5. The flow run is created successfully but it gets stuck in the

Pending

state. If I cancel the flow run and

Retry

it, it works fine and gets to the state

Completed

. Here is the request I’m doing:

curl -X 'POST' \
  '<https://my-prefect-dns/api/deployments/09147238-fe73-488a-8ba5-b545cd648519/create_flow_run>' \
  -H 'accept: application/json' \
  -H 'Content-Type: application/json' \
  -d '{}'

I am doing something wrong?

Hey David, here's an article which outlines some good first-steps to take when a flow gets stuck in

Pending

. Typically that means there was an error with the flow run deployment.

Thanks for the response Bianca, but my problem doesn’t seem related to any of those topics, since the flow run only gets stuck in the

Pending

state when I create it from the REST API request. If I create it from the UI it works just fine. Also if I cancel it and retry it, it also works. Right after I do the curl requests, the agent does not log anything, so looks like the agent does not know about the flow run, therefore it never goes to

Running

. The agent only logs something when I trigger the flow run from the UI or using the CLI.

Hey David, thank you for the additional context! The team has taken a more detailed look at this behaviour and we have created an issue to address it.

Awesome, thanks you so much!
