## Syntax

This tag has several usage styles, each style resulting in a valid action object.

  {
    "foo": "bar"
  }
{% enderror %}
```

### Tag syntax, single argument

```liquid
{% error "foobar" %}
```

{% assign details = hash %}
{% assign details["foo"] = "bar" %}

{% error message: "Something went wrong!", details: details %}
```
