Question

We re trying to get a POC going on Prefect 2 We have our infra setup but are having some issues running flows on task definitions It seems like this is happening First run of a flow gets the following error ```prefect aws ecs TaskFailedToStart Cannotpullcontainererror ref pull has been retried 1 time s failed to copy httpReadSeeker failed open unexpected status code <https registry 1 docker io v2 prefecthq prefect blobs sha256 209b7d3b67f9dca78847c83ea6f0a78b0f91672ea1ccedc00e9bd5eb46315807> 400 Bad Request``` 2nd and subsequent runs of the same flow gets a different error ```Flow could not be retrieved from deployment Traceback most recent call last File lt frozen importlib bootstrap external gt line 883 in exec module File lt frozen importlib bootstrap gt line 241 in call with frames removed File opt prefect flows atlan py line 5 in lt module gt from util import SnowflakeDestination File opt prefect flows util py line 3 in lt module gt import pandas as pd ModuleNotFoundError No module named pandas The above exception was the direct cause of the following exception ScriptError Script at flows atlan py encountered an exception ModuleNotFoundError No module named pandas ``` it appears that Prefect is creating a new task definition but it is not derived from our agent and therefore does not have the same dependencies installed How can we resolve this

Could you clarify what you mean by derived from our agent

Thanks for clarifying I meant derived from our agent s image I got an answer from <mailto support prefect io|support prefect io> on this last night If I understand it correctly anytime a block s Task definition parameters differ from the agent s task definition parameters Prefect spins up a separate task definition This then means that the new task definition may not have the needed dependencies Did I get that right
