Splunk DB Connect 3 migration: Why do I get a "ValueError: zero length field name in format" error?

Hi, There's been a couple of reports of this error when running the Splunk DB Connect 3 migration script: Traceback (most recent call last): File "./app_migration.py", line 907, in check_file_to_be_backuped(installed_apps) File "./app_migration.py", line 143, in check_file_to_be_backuped _copy_dir(from_dir, to_dir) File "./app_migration.py", line 121, in _copy_dir print("backup directory {} to location {}".format(from_dir, to_dir)) ValueError: zero length field name in format The reason for this error is that you're using the system Python instead of Splunk's Python. To avoid this issue, follow the directions at http://docs.splunk.com/Documentation/DBX/3.0.0/DeployDBX/MigratefromDBConnectv1#User_permissions Thanks!
