hi all - getting a strange behaviour: when running a flow on my (type Process) agent I have 2 stages under

pull

stage 1. cloning from git 2. installing requirements one of my flow requirements is boto3 (and obviously it is in the requirements.txt file) every first flow run after agent's startup fails with this error: "Flow could not be retrieved from deployment."

"exc_info":{"type":"ScriptError","message":"Script at 'flows/full_scan.py' encountered an exception: ModuleNotFoundError(\"No module named 'boto3'\")"

and the second flow onwards succeeds if I install boto3 manually on the agent's terminal it works fine

but if I add this step to pull:
- prefect.deployments.steps.run_shell_script:
    id: force-install-boto3
    script: python3 -m pip install boto3==1.28.0
    stream_output: true

the aforementioned behaviour continues help?

run_shell_script

added to your pull step? First flow run fails, then the next runs successfully?

@Bianca Hoch exactly

Quick follow up from our call - try using the k8s worker or process worker instead of an agent to see if the behavior changes in regards to the pull step

great will do
