Please open a support case.
Might be a dir or file permissions issue.
From Version 8.1.x (VER-42417) Vertica has improved admintools error message handling. Specifically, errors that caused admintools to issue the generic error message "'NoneType' object has no attribute 'getitem'" now include messages specific to the actual error.
