I have the same error, it is not posible to run the tickers and weights of a portfolio

Can you use a different way to generate the dictionary?
try

IAC = dict(SPY = 1.3, AGG = -0.3)

Also it would be useful if you can copy the output error code as a text and paste it in here.

I tried generating the dict as above, but to no avail... Here is my error code as text:
