PHP致命错误:无法重新声明Aws \ manifest()(之前已声明

I'm currently working with Wordpress, PHP and Docker. I'm trying to integrate the plugging s3-uploads. S3-uploads makes use of aws-sdk-php which is also used by another plugging mu-plugins/send-me-nyc which creates the conflict between the two.

When I run docker-wp s3-uploads verif I get the following error

PHP Fatal error:  Cannot redeclare Aws\manifest() (previously declared in /var/www/html/vendor/aws/aws-sdk-php/src/functions.php:342) in /var/www/html/wp-content/mu-plugins/send-me-nyc/third-party/AWS/Aws/functions.php on line 320
Fatal error: Cannot redeclare Aws\manifest() (previously declared in /var/www/html/vendor/aws/aws-sdk-php/src/functions.php:342) in /var/www/html/wp-content/mu-plugins/send-me-nyc/third-party/AWS/Aws/functions.php on line 320

So the error messages Cannot redeclare Aws\manifest() might be solve by a solution using !function_exist as stated on the linked post. However, I believe this is not the proper way to solve it since this would be writting on the code of aws-sdk-php directly. A patch like this was rejected from the admins of aws-sdk-php as shown in this Issue.

How can I go about solving this?
