cfn-init in aws cloudformation can't find metadata

Question

I'm setting up cloudformation stack with a PHP application and few other dependencies.

I am trying to setup configuration files and appliclation with metadata inside launch-configuration.

My code validates - no issues with yaml syntax and other part of stack is fine except for metadata part which cfn-init can't find.

I can confirm that cfn-init runs with the required params. But for some reason can't find metadata.

When I run aws helper cfn-get-metadata inside instance with the same params, I can see metadata all fine.

Any help? Here is my cloudformation snippet for metadata. I haven't included the userdata part that triggers cfn-init helper function.

Something as easy as this? Init vs init?
AWS::CloudFormation::init: vs AWS::CloudFormation:: I nit:
