Hi! I'm getting the following error when I am trying to run a flow locally through Prefect UI. I am launching both the

prefect server

and

prefect agent

from a directory where version

3.8.9

is active (I am using

pyenv

), so I don't know where this version

3.7.10

comes from. How can I tell which python version my agent uses? I assume, according to the error message, that the faulty version

3.7.10

is tied to the agent.

Failed to load and execute Flow's environment: StorageError("An error occurred while unpickling the flow:\n  TypeError('code() takes at most 15 arguments (16 given)')\nThis may be due to one of the following version mismatches between the flow build and execution environments:\n  - python: (flow built with '3.8.9', currently running with '3.7.10')")

Maybe you have a container you are running with Python 3.8.9?

3.8.9

is the expected version - i just don't know where

3.7.10

comes from given that it's not even installed on my computer.

What is base python version without pyenv?

3.9.7

Do you have a 3.7.10 somewhere in the pyenv? I was looking into pyenv and I might open an issue on Github to explore this deeper. I am not sure the local agent works with it. But that seems to be unrelated to your problem What type of agent are you using here?
