This doesn't appear to work when running the graph. I think we will need to refactor our conditional edges to rather use the command pattern. I'll take a look at this.

I also received this error when trying to use the functions in a Python node:

apps.pipelines.exceptions.PipelineNodeRunError: 'dict' object has no attribute 'get_all_routes'

This is because the state is actually just a dict and not an instance of PipelineState.
