Sample
sample application that reproduces the problem
https://github.com/firatsivrikaya/boot3.1.x-cloud-openfeign-awscloud-startup-issue

If I downgrade spring boot version to 3.0.11, application successfully starts.

PS: I don't know for sure if this is about spring cloud aws or spring cloud/open-feign
If I only include spring cloud aws, everything works, also; If I only include openfeign, everything works again. Somehow when I try to use both, application fails

@firatsivrikaya thanks for reporting. If you flip the order of dependencies it works as expected:

dependencyManagement {
	imports {
		mavenBom 'io.awspring.cloud:spring-cloud-aws-dependencies:3.0.2'
		mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
	}
}

This has been fixed in #916 and will be released in 3.0.3
