It seems like $answer can also be of type boolean and null and string; however, parameter $array of array_unique() does only seem to accept array, maybe add an additional type check?

                $hosts = $this->deployer->hosts->select(function (Host $host) use ($answer) {
                    return in_array($host->getAlias(), $answer, true);
                });
            }
        } else {
            $hosts = $this->deployer->selector->selectHosts($selectExpression);
        }

        if (empty($hosts)) {
            throw new Exception('No host selected');
        }

        return $hosts;
    }
