I get the following error

Traceback (most recent call last):

  File "/Users/rmaloney/Development/open-source/holoviz-dev/lumen/lumen/ai/coordinator.py", line 399, in _execute_graph_node
    await subagent.respond(custom_messages, step_title=title, render_output=render_output, **respond_kwargs)

  File "/Users/rmaloney/Development/open-source/holoviz-dev/lumen/lumen/ai/agents.py", line 230, in respond
    system_prompt = await self._render_main_prompt(messages)
                    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

    pipeline = self._memory["current_pipeline"]
               ~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^

  File "/Users/rmaloney/Development/open-source/holoviz-dev/lumen/lumen/config.py", line 64, in __getitem__
    return self._global_context[key]
           ~~~~~~~~~~~~~~~~~~~~^^^^^

KeyError: 'current_pipeline'

When I put a break point in the config file, and inspect the self._global_context object it returns an empty dictionary.
