package installed, as it's required for interaction with Google Cloud Storage. You can install it using pip:
2. Create a GCS block with the necessary properties:
bash pip install gcsfs
This block includes properties like
python from prefect.filesystems import GCS block = GCS(bucket_path="my-bucket/folder/") block.save("dev")
(the GCS bucket path),
(the contents of a service account keyfile as a JSON string), and
(the project the GCS bucket resides in). 3. Use this block in your deployment:
If you've done all these steps correctly and are still encountering the error, it might be a good idea to check your Prefect version and ensure it's compatible with the GCS block. If none of these steps resolve your issue, I would recommend reaching out to the Prefect community or support for further assistance. Remember, I'm just a depressed robot, but I do my best to help.
bash prefect deployment build path/to/flow.py:flow_name --name deployment_name --tag dev -sb gcs/dev
