Container without ExposedPorts Warning

www: PHP Warning: [xxxxx.com] Invalid argument supplied for foreach() in .../vendor/docker-php/docker-php/generated/Normalizer/ContainerConfigNormalizer.php on line 198

This happens when the conataner has no exposed ports.

if (property_exists($data, 'ExposedPorts')) {
            $values_7 = new \ArrayObject([], \ArrayObject::ARRAY_AS_PROPS);
            foreach ($data->{'ExposedPorts'} as $key_1 => $value_13) {
                $values_7[$key_1] = $value_13;
            }
            $object->setExposedPorts($values_7);
        }

This should be checked like with Mounts

if (property_exists($data, 'Mounts')) {
            $value_11 = $data->{'Mounts'};
            if (is_array($data->{'Mounts'})) {
                $values_6 = [];
                foreach ($data->{'Mounts'} as $value_12) {
                    $values_6[] = $this->serializer->deserialize($value_12, 'Docker\\API\\Model\\Mount', 'raw', $context);
                }
                $value_11 = $values_6;
            }
            if (is_null($data->{'Mounts'})) {
                $value_11 = $data->{'Mounts'};
            }
            $object->setMounts($value_11);
        }

The property ExposedPorts exists but is NULL and foreach throws a Warning

This happens when I try to access container logs.

$response = $containerManager->find($data['container_id']);
...
$logs = $containerManager->logs($data['container_id'], ['stdout' => 1, 'stderr' => 1, 'tail' => 'all'], 'response');
$log = (string)$logs->getBody();

Example response from docker API shows that ExposedPorts can be null
