probably this line:

const serviceRepo = ecr.Repository.fromRepositoryName(this, 'MedplumRepo', 'medplum-server');

Hardcoded medplum-server needs to get changed to something dynamic like:

cdk-hnb659fds-container-assets-926802560916-us-east-1

Or this:

docker build . -t $ECR_REPOSITORY:latest -t $ECR_REPOSITORY:$GITHUB_SHA

within the actual

deploy-server.sh

script.
