I tried to create yml file to use github actions for flutter web deployment.

But I face error saying Invalid action input '...'.

Output terminal shows below error.

I guess this error comes from prettier.

Because I write as ‘create-envfile’ official document say exactly same.

So I add .prettierignore on my root path and write code to ignore yml file.

*.yml

But the result is same.

I also added below line to settings.json.

 "[yaml]": {
    "editor.defaultFormatter": "esbenp.prettier-vscode",
    "editor.formatOnSave": false
  },

But still prettier throws errors.

How to avoid this error?
