# node-execute-block-wrong-error-thrown

The `execute()` method in a node may only throw `NodeOperationError`, `NodeApiError`, `TriggerCloseError`, `UserError`, `OperationalError`, `UnexpectedError`, or the deprecated `ApplicationError`.

📋 This rule is part of the `plugin:n8n-nodes-base/nodes` config.

## Examples

❌ Example of **incorrect** code:

```js
class TestNode {
	execute() {
		throw new Error("An error occurred");
	}
}
```

✅ Example of **correct** code:

```js
class TestNode {
	execute() {
		throw new NodeApiError(this.getNode(), "An error occurred");
	}
}

class TestNode {
	execute() {
		throw new NodeOperationError(this.getNode(), "An error occurred");
	}
}

class TestNode {
	execute() {
		throw new ApplicationError("An error occurred", { level: "warning" });
	}
}

class TestNode {
	execute() {
		throw new TriggerCloseError(this.getNode());
	}
}
```
