valueError (timeframe) when using get_ohlc_data()

[kitt-th]

Hello, when running the basic test code shown on the main page of the distro:

api = krakenex.API()
k = KrakenAPI(api)
ohlc, last = k.get_ohlc_data("BCHUSD")
print(ohlc)

The following error is raised.

Traceback (most recent call last):
  File "/Users/gg/opt/anaconda3/lib/python3.7/site-packages/pandas/core/arrays/datetimelike.py", line 893, in _validate_frequency
    raise ValueError
ValueError

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

Any help poss on how to fix this? Cheers
