Adding the following code to functions.php:

```auto
add_action('hivepress/v2/models/user/update', function($user_id, $user ) {

});

```

And then updating any field in User Settings screen raises the following error:

**Fatal error** : Uncaught ArgumentCountError: Too few arguments to function {closure}(), 1 passed in /home/public\_html/dev/wp-includes/class-wp-hook.php on line 309 and exactly 2 expected in /home/public\_html/dev/wp-content/themes/listinghive/functions.php:53

The same error occurs with:  
add\_action(‘hivepress/v1/models/user/update\_first\_name’, function($object\_id, $value ) {

});

If a custom callback you assign to a hook contains more than 1 parameter please specify the number of parameters this way:

```auto
add_action(‘hivepress/v2/models/user/update’, function($user_id, $user ) {

}, 10, 2);

```
