Newest Springboot 3.4.0 Hello World app not working when sending logs to LOKI (Grafana cloud) [Sample attached]

[patpatpat123]

Hello,

Before anything, just wanted to say thanks for this cool project.
I am trying to integrate this project with a very simple Springboot Hello World app.
However, logs are not being forwarded to LOKI.

Please find attached to this, a minimal reproducible.
Could you please download the project, unzip it and run it?
I have left on purpose the API keys of the Grafana Cloud instance
(It is a test instance, nothing secret here, it has been created with a dummy email. Please feel free to use it)

Could you please let me know what is the issue?

Thank you
