Bokeh quads 'got multiple values' error

I'm trying to plot a quad plot using Bokeh. The structure of the code that's giving me errors closely resembles what I have bellow. 

my_dict = {...} # has the following keys [left, right, bottom, top, color]

p = figure(width = 800, height = 800)

source= ColumnDataSource(data = my_dict)

p.quad(source,
       top="top",
       bottom = "bottom",
       left = "left",
       right = "right",
       color = "color")

This yields the following error: 

TypeError: quad() got multiple values for argument 'left'

The length of all lists in my dict are equal. I checked using: 

for key in my_dict.keys():
  print(len(my_dict[key ]))

I'm not sure how to proceed. I've also type checked each entry for 'left' to see if it was complaining about inconsistent typing. Any ideas?

The first argument to quad is not the data source:

http://docs.bokeh.org/en/latest/docs/reference/plotting.html#bokeh.plotting.figure.Figure.quad

It is left, which means in the code above, you are passing a value for left both as a positional argument (but giving it source as a value) as well as passing left as a keyword argument. This is exactly the situation that will cause Python to complain:

>>> def foo(arg): pass
...
>>> foo(10, arg=20)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: foo() got multiple values for keyword argument 'arg'

You need to pass source as a keyword argument (as all the examples demonstrate):

p.quad(top="top",
       bottom="bottom",
       left="left",
       right="right",
       color="color",
       source=source)
