Unable to use Spring cloud to connect with AWS SES - spring-boot

Question

I have made a very simple maven project using Spring Boot. I am trying to connect with AWS SES using Spring cloud. While running the project, I am getting following error:
No valid instance id defined
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.cloud.aws.core.env.ResourceIdResolver.BEAN_NAME': Invocation of init method failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'stackResourceRegistryFactoryBean' defined in class path resource [org/springframework/cloud/aws/autoconfigure/context/ContextStackAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.cloud.aws.core.env.stack.config.StackResourceRegistryFactoryBean]: Factory method 'stackResourceRegistryFactoryBean' threw exception; nested exception is java.lang.IllegalArgumentException: No valid instance id defined
I am showing snippets of files in use:

}
}
application.properties

I am not trying to connect to any EC2 instance. Not able to find any proper documentation for using spring cloud for SES

Answer 1

You've almost got it, you're just missing one more configuration flag to stop that exception creeping in.
Add cloud.aws.stack.auto = false to your application.properties file thus it will not enable the automatic stack name detection for the application.
You can read up more about it in the docs: http://cloud.spring.io/spring-cloud-aws/spring-cloud-aws.html#_cloudformation_configuration_in_spring_boot

Answer 2

Using the response of #Chris-Turner you can add a VM option to run your app locally:
-Dcloud.aws.stack.auto=false
