Fixed TypeError in Tracing issue with tokens that are dicts

[KronemeyerJoshua]

Description

In the latest version of OpenAI some keys have tokens that are not ints. This is causing TypeErrors like
TypeError: unsupported operand type(s) for +: 'int' and 'dict'
This aims to handle None types and Dicts better in tracing.

Should resolve bug #3834
