zipline example algo's fail on "JSONDecodeError" using docker image

[JOravetz]

Hi,

I successfully built the docker image and ingested the alpaca-bundle, as described in the documentation.

zipline ingest -b alpaca-bundle
Downloading Bundle: alpaca-bundle [####################################] 100%
Writing data to /root/.zipline/data/alpaca-bundle/2019-07-08T07;05;52.204324.

When running an example algorithm, however, I always get a json.decoder error (see below). Is this error coming from the ingested bundle or something different with regards to recent zipline issues? Please let me know if you are able to reproduce the error.

(using bash shell in alpaca-zipline docker image):

zipline run -f /work/examples/dual_moving_average.py --broker=alpaca --broker-uri=dummy --state-file /work/state --realtime-bar-target /work/realtime-bars --bundle alpaca-bundle --data-frequency daily --start 2015-1-1 --end 2016-1-1

Thanks very much for your attention to this. I would very much like to get zipline properly setup to continue porting my algorithms into Alpaca's trading platform.

quantopian/zipline#2480 problem is this but implementing the fix from docker will be a bit of a pain
