Hey @Vardhan, you're missing out on the requirements mentioned in the Documentation. You need Boto to be installed on your Server as well as the client.
You can install it via the python package manager
$ pip install boto --user
If you are using linux you can also install it via the package manager:
# RHEL/CentOS
$ sudo yum -y install python-pip
# Fedora
$ sudo dnf -y install python-pip
