Hi Prefect Experts - Im running 1.X of Prefect and run into the dreaded

"No heartbeat detected from the remote task"

issue a few times and its well documented here to consult https://discourse.prefect.io/t/flow-is-failing-with-an-error-message-no-heartbeat-detected-from-the-remote-task/79.

I didn’t see it explicitly stated, but is setting

flow.run_config = UniversalRun(env={"PREFECT__CLOUD__HEARTBEAT_MODE": "thread"})

Copy code

[cloud]
heartbeat_mode = "thread" # ['process', 'thread', 'off']

supported when running Prefect on premise

I think the second option will work if you have that config file on the same machine as your agent

I think the first is clearer, though.

Thanks, I just wanted to confirm it wasn’t only respected when running cloud.

I guess I should have looked at the settings first.

Ah yes the ‘cloud’ key applies to both backends

It’s a holdover from before server was split out and open sourced and remains for backwards compatibility.
