Hi everyone 👋 I’m trying to run a Flow locally, with a local agent and can’t get it past the “Submitted for execution” state.. Tried a lot of different stuff: • shutting down the agent (though this seems like something not very well documented, please correct me if I’m wrong) • matching the labels of the agent and the flow • switching things up with the environment variables (and Secret()) In the agent logs this is the error I get. The messed up thing is that everything was running smoothly 2 days ago..

Hey @Jovan Sakovic, maybe running with debug level logs on the agent would help. Hard to tell but it’s definitely not the labels cuz the agent is picking it up.

Hi @Kevin Kho, thanks for the tip Though not much different is logged

I assume the flow doesnt start right? What is the state in the UI?

Correct. “Submitted for execution:

Do you know if this is flow specific or all flows?

Let me try a very simple example flow Had the same issue with a different flow an hour ago, fiddled around with agents and it worked out. Though I guess it was just a lucky shot

If the simple one fails, you probably need to check that server containers are all alive.

Okay, running the simple one gets us a step closer In my project, I have a prefect directory. In it there’s a script with a flow, and another slack_metadata script. The latter is imported in the flow script. Because of this, I’ve been getting the following error:

Failed to load and execute Flow's environment: FlowStorageError('An error occurred while unpickling the flow:\n ModuleNotFoundError("No module named \'slack_metadata\'")\nThis may be due to a missing Python module in your current environment. Please ensure you have all required flow dependencies installed.')

To get around that, I made a

__init__.py

in the prefect directory (where the flow and metadata script are). Now, after trying the simple example, I assume that prefect saw the prefect directory as the prefect module, and could not import any of the prefect imports..

Yeah you can start your agent in the same directory where it is importable, or use the

LocalRun

RunConfig that lets you choose a working directory to run the flow. If that init ends up not being called, I guess you would need an explicit import. I’m not sure it will be called.

That’ll do it.. Thank you!
