Cloud config returns 404 not found if the label is empty

[ahmadsab95]

Spring Cloud Config support empty label when using 2.1.6.RELEASE , in case it empty the cloud config server use the default label

once upgraded to 3.1.1 , it does not accept empty label from client and return 404 not found instead of use the default label

i just noticed that the request deleted , but i don't understands why ? and if its not supported what the purpose of the default label that set by the config server

@RequestMapping("/{name}/{profiles:.*[^-].*}")
public Environment defaultLabel(@PathVariable String name,
		@PathVariable String profiles) {
	return labelled(name, profiles, null);
}

Facing the same issue with Spring Cloud 3.1.3, was in the process of migrating all my services from older (yet compatible Boot and Cloud versions) and unless I specifically declared the label name, my services do not seem to pick up configuration from the Config server at all (trying to migrate to Spring Boot 2.7.2 and Spring Cloud 2021.0.3)
