IndexError: too many indices for array: array is 1-dimensional, but 3 were indexed

Expectation The program below would run to conclusions without errors or it would clearly and consisely log a setigen limitation before throwing an exception.

Input file https://storage.googleapis.com/ata_test_data/turbo_seti_test/guppi_59196_68468_000762_Unknown_0001.rawspec.0000.h5

My program

import setigen as stg
from setigen.waterfall_utils import min_freq, max_freq
from blimpy import Waterfall

DIR = '/seti_data/turbo_seti_issue_135/'
INFILE = DIR + 'guppi_59196_68468_000762_Unknown_0001.rawspec.0000.h5'


def import_bl_file(path_infile):
    r'''
    Using setigen, import a BL file (.fil, .h5).
    '''
    print('Input file:', path_infile)
    wf = Waterfall(path_infile)
    print('Waterfall data loaded?', wf.container.load_data)
    print(wf.info())

    # Instantiate a setigen Frame object
    frame = stg.Frame(waterfall=wf)
    print('Drift rate:', frame.get_drift_rate(0, -1))
    print('Noise stats:', frame.get_noise_stats())
    print('min freq:', min_freq(wf))
    print('max freq:', max_freq(wf))
