# Throw Error

> Fail the current workflow run with a custom message.

## Input

| Input       | Type   | Required | Description                         |
| ----------- | ------ | -------- | ----------------------------------- |
| **Message** | String | Yes      | The error shown for the failed run. |

When this action executes, it throws immediately. Actions that depend on its
completion do not run.

Use it after validation or a failure branch:

```text theme={null}
Required value is missing
  → Throw Error: "Customer ID is required"
```
