Jiening Wen updated AIRFLOW-1465:
---------------------------------
    Description: 
The example on 
https://airflow.incubator.apache.org/profiling.html#chart-screenshot fails with 
error message like {{1496268000000 is not JSON serializable}}.

!chart error.PNG|thumbnail!

It seems to be related to an upstream issue in pandas that Index.tolist doesn't 
convert values to python native types.
