Define correct type for field helper doc

[laoneo]

The $item parameter FieldsHelper::getFields has to be an object or array and not null.

The $item parameter FieldsHelper::getFields has to be an object or array and not null.

I don't understand this, because in line 108 $item gets the value null? You probably mean something else.

joomla-cms/administrator/components/com_fields/src/Helper/FieldsHelper.php

Line 108 in 37df313

$item = null,

In line 128 I can see that the variable $item can be an array.

joomla-cms/administrator/components/com_fields/src/Helper/FieldsHelper.php

Line 128 in 37df313

if (is_array($item)) {

How can I best test this PR?

[laoneo]

Use a debugger and check the types of $item while working with custom fields. But as you can see in the code, it can be an object, array or null. The doc comment is wrong as it can, but not must, be null.

If you want to test something as this one here is just cosmetic, better to look at #42473.
