Every issue in a written network, all at once: someone who writes from an example needs the whole list, not the first mistake. An empty list means the network can be read.

```
checkNetwork(value: unknown): NetworkIssue[]
```

## Parameters

| Parameter | Type | Description | Default |
| --- | --- | --- | --- |
| `value` | `unknown` | No additional description. | `—` |

## Returns

```
NetworkIssue[]
```
