Hi, I have followed along with the readme below to setup a Jupyter notebook through the provided docker container.  I generated an API key and filled in the relevant config.json fields for job-user-id and api-access-token.

When I run a slightly modified version of the example template, I get an empty history result:

Below is a screenshot of the empty Pandas dataframe returned by qb.History. The cell with api.Connected shows that there is a connection to the web api.

Any ideas what might be wrong?
