[s3fs] S3 File System

For some simpler use cases the Flysystem module (D8 ready) may provide adequate integration with Amazon S3.

I'm trying to use this module in Drupal 8, After successful installation and configuring the credentials, i have following fatal error thrown

Fatal error: Call to a member function getObjectUrl() on null in \modules\contrib\s3fs\src\StreamWrapper\S3fsStream.php on line 474

I config s3 using settings.php like this :
/**
* Config AWS SDK
*/
$config['awssdk.configuration']['aws_key'] = getenv('S3ACCESSKEY');
$config['awssdk.configuration']['aws_secret'] = getenv('S3SECRETKEY');
/**
* Config S3 File System
*/
$settings['s3fs.access_key'] = getenv('S3ACCESSKEY');
$settings['s3fs.secret_key'] = getenv('S3SECRETKEY');
$config['s3fs.settings']['bucket'] = getenv('S3BUCKETNAME');
$config['s3fs.settings']['region'] = getenv('S3REGIONNAME');
$config['s3fs.settings']['use_https'] = TRUE;
$settings['s3fs.use_s3_for_public'] = TRUE;
$settings['s3fs.use_s3_for_private'] = TRUE;
$settings['s3fs.no_rewrite_cssjs'] = FALSE;
$config['s3fs.settings']['encryption'] = 'AES256';
$config['s3fs.settings']['public_folder'] = getenv('PUBLIC_FOLDER');
$config['s3fs.settings']['private_folder'] = getenv('PRIVATE_FOLDER');
$settings['s3fs.use_cname'] = TRUE;
$settings['s3fs.domain'] = $_SERVER['HTTP_HOST'];
$config['s3fs.settings']['root_folder'] = 'XXXXX';
then I use validate in Actions Tab of Config Files and it's validate with out any problem but when i try to copy file using button in Actions tab no files copy and I redirect to Home page with this:
Notice: unserialize(): Error at offset 19629 of 43474 bytes in Drupal\Core\Batch\BatchStorage->load() (line 71 of
core/lib/Drupal/Core/Batch/BatchStorage.php).
No active batch.
also when i try to run drush s3fs-copy-local i face with this :
[warning] You should have read "Copy local files to S3" section in README.txt.
[warning] This command only is useful if you have or you are going to have enabled s3 for public/private in your setting.php

Are you sure? (yes/no) [yes]:
