I’m getting an error “File system ... could not be created. You are likely missing a Python module required to use the given storage protocol” - how to solve that?

There are several ways you can solve that problem:

1. Install the required file-system subpackage in your environment, e.g.:

pip install s3fs
pip install gcsfs
pip install adlfs

2. Include it as environment variable called EXTRA_PIP_PACKAGES - works only for DockerContainer block - docs

3. Build a custom image with those dependencies - you can use this GitHub Actions workflow template to build and push such custom DockerHub image in a single click:

You can configure and trigger the image build process directly from the GitHub Actions UI:
