    Raised when the graph has exhausted the maximum number of steps.

    This prevents infinite loops. To increase the maximum number of steps, run your graph with a config specifying a higher recursion_limit.

    Troubleshooting guides:

    • GRAPH_RECURSION_LIMIT

    Examples:

    graph = builder.compile()
    graph.invoke(
        {"messages": [("user", "Hello, world!")]},
        # The config is the second positional argument
        {"recursion_limit": 1000},
    )
