# Default Sender Errors

You can set default `failedPermissions` and `failedArguments` functions like this:

```javascript
ds.defaultFailedPermissions(({send}) => {
    send('You don\'t have the permissions to do that!');
});

ds.defaultFailedArguments(({send}) => {
    send('Incorrect arguments!');
});

ds.defaultFailedCooldown(({send, timeleft}) => {
    send(`You need to wait ${timeleft}s!`);
});
```
