I keep getting this error when trying to have a scheduled run from a deployed flow. It runs fine as a non-deployed flow (when I run it from my terminal). I built and applied the deployment on another flow/script and it worked (but it also doesn’t have any non-prefect imports). Should I

import psycopg2

from somewhere else instead? Running 2.3.2

Flow could not be retrieved from deployment.

Hey @kiran 👋 what infrastructure are you using for your deployment? I'd guess that you might be using the prefect base image that doesn't have psycopg2 installed, whereas you do have it installed locally to check this theory, you could add

{"EXTRA_PIP_PACKAGES": "psycopg2"}

to the

env

section of your infrastructure block, which will install it each time the flow runs (somewhat inefficient) and then the cleanest solution would be to

pip install psycopg2

wherever your flows will run (i.e. from your

requirements.txt

in a Dockerfile or in a venv on some VM where your agent runs)
