If you're going to use a $request->input() in a foreach(), be sure to include a fallback if nothing is passed. If nothing is passed, $request->input() is null, and foreach(null as $node) is not valid.

If you add a fallback, it will use that instead (in your case, an array):

$request->input('publicIds')     // `null`
$request->input('publicIds', []) // `[]`

So, to make your code type-safe for a foreach(), do the following:

foreach ($request->input('publicIds', []) as $node) {
  print($node);
}

In scenarios where $request->input('publicIds') is null, it will fallback to an array. If scenarios where $request->input('publicIds') is already an array, the fallback will be skipped (as it is already an array), and your code is now safe.
