Uncaught count error from CodeGenerator because of null value in regexes

[RemiRiu95]

Hello,

Following the commit from 3 days ago: ae4c16d
adding on line 2513

regex: 'CrKey/'
brand_replacement: 'Google'
device_replacement: 'Chromecast'
model_replacement: null

and more specifically model_replacement: null,

the command php vendor/ua-parser/uap-php/bin/uaparser ua-parser:update no longer works, throwing:
Uncaught TypeError: count(): Argument #1 ($value) must be of type Countable|array, null given in vendor/ua-parser/uap-php/src/Util/CodeGenerator.php:44

Is it possible to secure this count on your side ?

Thank you very much.
