What happened?

I receive values to a page which I need to parse into an array. I am using $this->request->getPost([ ... ]) to ensure that only the values I require are parsed. This works as expected.

I have an instance where the same page is called with values being passed via the query string so I use $this->request->getGet([ ... ]) to parse the query string.

I don't know whether the request is going to come via GET or POST so naturally I would like to use $this->request->getPostGet([ ... ]) however an error is thrown instead.

Steps to Reproduce

$values = $this->request->getPost([ 'IPAddress' ]);
print_r($values);

// Array ( [IPAddress] => NULL )

$values = $this->request->getGet([ 'IPAddress' ]);
print_r($values);

// Array ( [IPAddress] => NULL )

$values = $this->request->getPostGet([ 'IPAddress' ]);
print_r($values);

// Expected -- Array ( [IPAddress] => NULL )

Expected Output

When I run $values = $this->request->getPostGet([ 'IPAddress' ]); I expected to get an array as I do with getGet() or getPost(), however an error is thrown instead:

TypeError
CodeIgniter\Superglobals::post(): Argument #1 ($key) must be of type string, array given, called in [Folder]\vendor\codeigniter4\framework\system\HTTP\IncomingRequest.php on line 604

The same happens if I call $this->request->getGetPost([ ... ])

Anything else?
