Need help to validate a YAML file using a schema

[odebroqueville]

I created a file named .pls.yml with the code below in my ~ home directory on Mac. I would like to validate the file with the schema provided by the url below. I installed the YAML extension for VS Code but nothing is happening. Can someone please explain what I'm missing. Thank you.

# yaml-language-server: $schema=https://raw.githubusercontent.com/dhruvkb/pls/main/src/pls/data/schema/pls_config.yml

P.S. I've been trying to follow the instructions on this page.

The small example you have posted seems to work for me. Could there be an issue with the network connectivity? As vscode-yaml needs to be able to download the schema. Perhaps a proxy?

@gorkem My fault! I hadn't understood how to use the YAML validation. If I make an error in the YAML file, it gets reported under Problems in VSC. Therefore, I assume things are working properly.

Sorry for my misunderstanding: I wasn't seeing anything happen because my YAML file didn't contain any errors!

That does not still sound right. It should also show a red mark on the side for that line. But it looks like vscode-yaml is reporting the error as expected.
