PHP 8 issue using the module into Magento 2.4.5 context

[gianstraf]

Hi,
due to the use of module on PHP 8.1 we have found a problem into

KnownUser.V3.PHP/UserInQueueStateCookieRepository.php

Line 60 in 7aa77ab

$cookieNameValues = explode("&", $cookieValue);

and

KnownUser.V3.PHP/UserInQueueStateCookieRepository.php

Line 64 in 7aa77ab

$arr = explode("=", $cookieNameValues[$i]);

when the second param is null (PHP Deprecated: explode(): Passing null to parameter #2).

Same problem here:

KnownUser.V3.PHP/UserInQueueService.php

Line 224 in 7aa77ab

if (substr($queueDomain, -1) !== "/")

with substr function (PHP Deprecated: substr(): Passing null to parameter #1).

In our context, the module required by queueit/knownuser throws an error when used on the Magento 2.4.5 context (magento/magento2#35875).

Thank you
