Unable to ingest AlphaVantage API Data

[earlcharles1]

The documentation only supplies instructions for ingesting data with Alpaca's API. I have followed all of the instructions, but I'm faced with a TypeError: an integer is required (got type bytes). Do any of you use zipline with AlphaVantage? Or should I just go to Alpaca?

Code: \src>python zipline-trader/zipline/data/bundles/alpha_vantage_api.py

Error:

File "c:......\src\zipline-trader\zipline\utils\preprocess.py", line 246, in _build_preprocessed_function

new_func.code = CodeType(*map(getitem(args), _code_argorder))

TypeError: an integer is required (got type bytes)

I get this error also using Alpaca. Any help would be really appreciated.
