Is there a way to return a Metaflow run id to the caller in Python subprocess.call() while the flow is still running? I am aware of --run-id-file option but it gets written to that file after the flow is completed/errored. I need that run Id while the Flow is still running.

--run-id-file

should get written immediate when the run starts. You can add a

time.sleep

in your

start

step to confirm this. You should see the file while the

start

step is sleeping

Thanks @straight-shampoo-11124 for the reply. That works!

great!
