Store the error output of a command in shell script

I am able to store the output of a command when it completes successfully.
example

#!/bin/sh
createimage=$(aws ec2 create-image --instance-id i-bb68f5df --name ftp.b2b.backup.12-1 --no-reboot --description ftp.b2b.backup.test)
echo "$createimage"

script returns
{
    "ImageId": "ami-f5113e9c"
}

however when the command fails in the script the output is not being stored in the createimage variable.
