On line 39 of stream.py, the rs parameter is set as follows:

'rs': ''.join(random.choices(string.ascii_uppercase + string.digits, k=10)),

However, the import statement on line 2 is

from random import random

With this import statement, the symbol random refers to the function rather than the library, and it is the library which has the choices function.

This problem causes a crash with AttributeError: 'builtin_function_or_method' object has no attribute 'choices' when get_snap is called.
