$arr was never initialized. Although not strictly required by PHP, it is generally a good practice to add $arr = array(); before regardless.

It seems like $paths can also be of type string; however, parameter $value of count() does only seem to accept Countable|array, maybe add an additional type check?

The expression return $message returns the type string which is incompatible with the return type mandated by Meema\CloudFront\Contracts\CloudFront::getInvalidation() of Aws\Result.
