finnhub-python: Latest version on PyPi doesn't fetch stock candles

I recently discovered that the library that I was using previously is no longer being served by PyPi, and the project has been archived on Github (https://github.com/s0h3ck/finnhub-api-python-client). So, I switched to this client library.

Unfortunately, however, it doesn’t appear to be working properly. When fetching data using the stock_candles method (for any stock that actually has data), the following result is returned:

{'c': None, 'h': None, 'l': None, 'o': None, 's': None, 't': None, 'v': None}

So, I’m currently just using the python requests library and hitting the REST endpoints directly, which obviously isn’t as convenient.

Any thoughts would be appreciated.
