@Marvin how do i clear the credentials cache for prefect.filesystems.GCS?

To clear the credentials cache for Prefect's integrations with Google Cloud Storage (GCS), the documentation doesn't seem to specify a direct method for clearing the credentials cache. However, managing credentials usually involves creating a Credentials Block with your GCS service account information and then using it within your flows. When setting up or updating credentials, it is recommended to pass the service account key details as a string directly rather than the path to the key file. This ensures that the file is not required at runtime, which might be helpful if your production environment does not have access to the key file directly. Here's a general approach to manage your GCS credentials within Prefect: 1. Set your GCS service account key as an environment variable or securely within Prefect's secret store. 2. Create a

GCPCredentials

block with those credentials, making sure to set

overwrite=True

if you want to update the existing credentials block. Here's an example of creating a

GCPCredentials

block:

python
import os
from prefect_gcp import GCPCredentials

my_gcp_creds = GCPCredentials(
    service_account_info=os.environ.get("GCP_SERVICE_ACCOUNT_KEY_FILE_CONTENTS"),
)
my_gcp_creds.save(name="my-gcp-creds-block", overwrite=True)

If you want to clear the cache entirely, you may need to delete the credentials block and remove any environment variables or Prefect secrets that may be caching your GCS credentials. Below are the references to the documentation where these concepts are mentioned: - Moving Data - Prefect Docs - Work Pools - Prefect Docs - Storage Guide - Prefect Docs Please note that these references don't explicitly mention clearing a credentials cache, but they discuss managing and creating a credentials block, which is typically where credentials are stored and used by Prefect when interacting with GCS. The solution I provided is extrapolated from general practices for managing cloud authentication in code.
