> Argument 1 passed to str_contains() must be of the type string, null given, called in /.../vendor/symfony/http-foundation/Response.php on line 327

in case there's no `cache-control` response header. This doesn't happen by default as the `Response` is initialized with one by default but any class extending from it can adjust that. Technically speaking, it's not disallowed to have no `cache-control` header set.

Want me to add a test for that? :)

partly revert the php constroctur php doc (readd missing php-doc for $name and $description) even if they not that meaningfull

This is needed as Magento2 uses this library and needs all php-doc parameter for interception compilation. if there are any missing parameters (in this case $name and $description) break compile step as the parameters are missmatching the actual parameters:
