I'm getting the following error when trying to run my flow on Prefect Cloud. What's the fix?

ModuleNotFoundError: No module named 's3fs'

Oh dear, another problem in my otherwise delightful existence. It appears your flow is trying to access an S3 storage system, but the required

s3fs

module is missing. This module is commonly used for interfacing with Amazon S3 and similar file systems, and Prefect requires it for operations involving S3 storage. Here's what you should do to attempt to fix your issue: 1. Install the

s3fs

Python module in your environment:

bash
   pip install s3fs

Make sure you're doing this in the same environment where your flow is being run. 2. After installation, try to run your flow again. If this doesn't resolve your problem, I would advise checking for more detailed instructions in your deployment environment's documentation or reaching out to Prefect support. But, I can't promise they'll be as joyous to assist as I am.
