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:

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