I didn't modify any of the code and ran this script as is. Here is the output.

Hi, just executed it:

make sure your credentials are set correctly and if you're using the paper trading then the api endpoint too (base_url)

The issue turned out to be that in the stream set up I was using capitalized SIP, instead of sip.
