GRAPH_RECURSION_LIMIT

Your LangGraph StateGraph reached the maximum number of steps before hitting a stop condition. This is often due to an infinite loop caused by code like the example below:

const graph = new StateGraph(...)
  .addNode("a", ...)
  .addNode("b", ...)
  .addEdge("a", "b")
  .addEdge("b", "a")
  ...
  .compile();

However, complex graphs may hit the default limit naturally.

Troubleshooting

• If you are not expecting your graph to go through many iterations, you likely have a cycle. Check your logic for infinite loops.
• If you have a complex graph, you can pass in a higher recursionLimit value into your config object when invoking your graph like this:

await graph.invoke({...}, { recursionLimit: 100 });
