When using --environment=conda, if I specify a conda_base for the flow but also specify a specific image for a step using @batch(image=xyz), I get the following error

bash: line 1: metaflow_FlowName_linux-64_sha/bin/python: No such file or directory

The docker image I'm using is a custom python:3.10-slim image where I have installed some python packages with pip into a venv with then added that venv to the path. So, conda isn't installed. I'm assuming that's the issue. Am I right, or is there something else going on?
