08/02/2021, 9:51 AMHi, I am trying to set up a flow with Azure storage and AKS for the agent and cloud server. The flow registers but when I try to quick run it I get the error 'Failed to load and execute Flow's environment: AttributeError("'NoneType' object has no attribute 'rstrip'") - not sure what I am doing wrong

08/02/2021, 9:57 AMHi Jai, this seems like a configuration problem with Storage and execution. May I ask what execution environment did you use? (Docker, k8s, or local machine)

08/02/2021, 10:16 AMThere’s two potential issues I’d like to explore more,
1. Some tasks involved with a relative path, which cause the error when the agents is running in different file path. (not in your root directory) - this can be fixed by getting rid of relative path
2. The storage didn’t load in successfully, so you used local storage by accident. *less likely to be true since you used Azure storage, should be easy to verify if the Azure storage is working!

08/02/2021, 10:17 AMMaybe a good way to investigate is to check where did you call

08/02/2021, 10:39 AMI don't actually use .rstrip at all - that probably some internal prefect routine

08/02/2021, 1:15 PMHey Jai - good point, that’s something from Prefect. I found a relevant issue that has similar problem - @ciaran mentioned a solution of putting the azure storage in RunConfig to solve this problem:
Copy code
run_config=KubernetesRun(
image="prefecthq/prefect:0.14.17-python3.8",
env={"AZURE_STORAGE_CONNECTION_STRING": os.environ["FLOW_STORAGE_CONNECTION_STRING"]},
labels=json.loads(os.environ["PREFECT__CLOUD__AGENT__LABELS"]),
),Yueh-Han
08/02/2021, 1:15 PMDo you think that could be a promising solution?
