I ran into the exact same problem.
Ubuntu 22.04.4 LTS x86_64
Docker compose version v2.25.0

But I don't think the docker version matters, because if I justs do 'docker compose up' from the commandline with the same generated file (as in the logs), it works fine.
From the logs it seems as if the parser expects the file to be in json format instead of yaml?

Same problem on OpenSuse Tumbleweed ver. 20240321 x64
Docker Compose version 2.25.0
Docker version 25.0.3-ce, build f417435e5

Few days ago was working. I think after updating OS/Docker something broken.
Spring Boot 3.2.4

I think this is a duplicate of #40060
