Spring Cloud Config url /{label}/{application}-{profile}.properties stopped working in spring boot 2.6.1 and config 3.1.0

I upgraded spring cloud to 2021.0.0 and spring boot to 2.6.1 and it stopped working for URL in format /{label}/{application}-{profile}.properties.

It ends with this response:

{"name":"master","profiles":["app-devt.properties"],"label":null,"version":null,"state":null,"propertySources":[]}

I tried to debug it and it goes to this method in the controller instead of the correct one.

Can you provide a complete, minimal, verifiable sample that reproduces the problem? It should be available as a GitHub (or similar) project or attached to this issue as a zip file.

I think the old behavior should return if the property spring.mvc.pathmatch.matching-strategy: ant_path_matcher is set.

Comment From: SamuelTissot

I can confirm that spring.mvc.pathmatch.matching-strategy=ant_path_matcher fixed the issue
