# GRAPH_RECURSION_LIMIT

Your LangGraph [`StateGraph`](https://langchain-ai.github.io/langgraph/reference/graphs/#langgraph.graph.state.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:

```typescript theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
import { StateGraph, StateSchema } from "@langchain/langgraph";
import { z } from "zod/v4";

const State = new StateSchema({
  someKey: z.string(),
});

const builder = new StateGraph(State)
  .addNode("a", ...)
  .addNode("b", ...)
  .addEdge("a", "b")
  .addEdge("b", "a")
  ...

const graph = builder.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:

```typescript theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
await graph.invoke({...}, { recursionLimit: 1000 });
```
