Template Yaml not working very well

I'm using the github template to create an instance on AWS and pre-configure the database, but without commenting on this section the error "Neo4jAutoScalingGroup" occurs
Type: AWS::EC2::Instance
# CreationPolicy:
# ResourceSignal:
# Timeout: PT12M
# Count: 1
Even though I comment, I still have a problem, because the instance is created but the neo4j pre-configuration is not done, I need to install it via yum and also install the plugins, which the template should already do. I need to understand what I need to do so that the pre-configuration is done and I can just load the dump
