InvalidAMIID.NotFound when Executing automation

Question

I am following this [blog](https://aws.amazon.com/blogs/robotics/robotics-development-in-aws-cloud9/) to create an AWS Cloud9 instance integrated with ROS Melodic and Gazebo9. When I execute the automation of the Systems Manager document however, the first step "startInstances" fails and this error pops up:
>Automation Step Execution fails when it is launching the instance(s). Get Exception from RunInstances API of ec2 Service. Exception Message from RunInstances API: [The image id '[ami-0e472ba40eb589f49]' does not exist (Service: AmazonEC2; Status Code: 400; Error Code: InvalidAMIID.NotFound; Request ID: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx; Proxy: null)]. Please refer to Automation Service Troubleshooting Guide for more diagnosis details.

I have seen that the ami-0e472ba40eb589f49 is the one referred in the SSM for ROS Melodic file, but the error message says I don't have this image.
How can I solve this problem?

Accepted Answer

Thanks for the detailed description.

May I know if you are running in the same `us-east-1` region as in the blog? The image `ami-0e472ba40eb589f49` is only available in that region. To find alternative AMIs in other regions, perhaps you could search for `ubuntu/images/hvm-ssd/ubuntu-bionic-18.04-amd64-server-20211129` and replace the AMI ID in the document content.
