filename The name of the file
mime.type The MIME type of the file
drive.size The size of the file
drive.timestamp The last modified time or created time (whichever is greater) of the file. The reason for this is that the original modified date of a file is preserved when uploaded to Google Drive.

    Processor Configurations
    org.apache.nifi.processors.gcp.drive.ListGoogleDrive
    The "Folder ID" property should be set to the ID of the Google Drive folder that files reside in.     See processor documentation / additional details for more information on how to determine a Google Drive folder's ID.
    If the flow being built is to be reused elsewhere, it's a good idea to parameterize     this property by setting it to something like `#{GOOGLE_DRIVE_FOLDER_ID}`.

The "GCP Credentials Provider Service" property should specify an instance of the GCPCredentialsService in order to provide credentials for accessing the folder.

The 'success' Relationship of this Processor is then connected to FetchGoogleDrive.
    org.apache.nifi.processors.gcp.drive.FetchGoogleDrive
    "File ID" = "${drive.id}"

The "GCP Credentials Provider Service" property should specify an instance of the GCPCredentialsService in order to provide credentials for accessing the bucket.
