I use VS code. I am starting a new project that is using GitHub Actions. I am using Red Hat's YAML extension.
It usually works great. It says that is has support for GitHub Workflows and GitHub Actions. But it is very "confused" regarding what should be highlighted. The code in the screenshot below works - I have deployed successfully - and it is messing up very obvious highlighting. In the screenshot, I am hovering over elements in the env list and you can see that it is saying that environment variables must be booleans. (FWIW, I also tried putting in a boolean and then it complained about it not being a key-value pair, which is actually correct.)
It appears that others are also having this problem and there was a suggestion given here that should have fixed it but didn't.
Has anyone else had trouble setting up GitHub Actions syntax highlighting?
