Initialize runtime.context when using langgraph CLI

Hi, I am playing around with LangGraph templates, and I’ve noticed some issues with runtime.context. As a default since langgraph>0.6.1, this context is None so it can’t be accessed without being set (in version 0.6.0 which introduced this feature, it seems that it was initialized to an empty dictionary but not in later versions.
This will lead the basic template to fail with an error, I’ve documented the issue here: Runtime context is not initialized as a default · Issue #14 · langchain-ai/new-langgraph-project · GitHub

My problem is that setting context seems to be done at invokation time: however, when using langgraph dev, I don’t have control on the invoke call.
Documentation about context showing the invoke call with a context param : Context overview - Docs by LangChain and Runtime.

How can I initialize the context when using LangGraph CLI?
