This seems caused the aws sdk version conflict, the agent only use 2.9.2 for the most recent release, while the aws sdk exists on your host is 2.9.44. There are two ways you can migrate this temporarily:

1. update the agent code as what you've done here

2. Upgrade to the most recent host agent(currently support 2.9.2), and then install 2.9.2 aws sdk
