Accessing Graph state on GraphRecursionError

[balvisio]

Is there a way to obtain the graph state when handling the GraphRecursionError:

try:
    res = self.graph.invoke({"query": query}, config={"recursion_limit": 1})
except GraphRecursionError:
    # I want to read the state here
    logger.exception(f"The invocation to graph reached the recursion limit")

Thank you!

If I were doing this, I would fetch the state from the last checkpoint:

graph = builder.compile(checkpointer=...)
config = {"configurable": {"thread_id": "abcd123"}}
try:
    res = self.graph.invoke({"query": query}, config={"recursion_limit": 1, **config})
except GraphRecursionError:
    # I want to read the state here
    logger.exception(f"The invocation to graph reached the recursion limit")
    state = self.graph.get_state(config)

Thank you!

Are there any other way w/o using checkpoint? I don't want to implement a checkpointer but just want to log the messages to my error tracker when error occurs. Including the last state in the exception object might be a better idea.
