I am trying to extend google assistant to be able to use my own local commands, it is working, but the voice still responds with "I can't help you with that" or something similar. When I try to use the stop_conversation() method I get an error:
TypeError: unbound method stop_conversation() must be called with Assistant instance as first argument (got nothing instead)
How can I fix this?

Here is a code that i moded for my google assistant project and i guess this is what you are looking for. The stop_conversation should be called along with assistant function, else it will spill out errors.
