Cannot find a definition for command named aws-ecs/deploy_service_update in CircleCI config.yml for Docker AWS ECR ECS setup

Question

In CircleCI, I am trying to build my Docker image and push it to AWS ECR and then deploy with AWS ECS. However, for the AWS ECS part, I am getting an error in CircleCI:

Error: config compilation contains errors: config compilation contains errors:
        - Error calling workflow: 'build_deploy_prod'
        - Error calling job: 'deploy-to-ecs'
        - Cannot find a definition for command named aws-ecs/deploy_service_update

I find that the AWS ECR part does not have any problems and is working correctly, however I get this error only for the AWS ECS deploy_service_update.

Here is the code for my CircleCI config.yml:

I have tried the service name with both hyphens and underscores. I tried to set it up using the documentation on CircleCI website:

Look at the list of commands for the aws-ecs@5.1.0 orb. None of them is called "deploy_service_update".

The "deploy_service_update" you see in the orb's documentation is how that specific usage example was named.
