[Bug]: Error with prettier 3.0.0

[drackp2m]

How did you encounter this bug?

A couple of days ago prettier version 3 was released. It always tends to update dependencies as often as I try to remember.

When I did it this morning for the last time, the plugin throws me an error (pasted in debug section) when trying to format a scss file.

My package:

{
		"eslint": "8.44.0",
		"eslint-config-prettier": "8.8.0",
		"eslint-import-resolver-typescript": "3.5.5",
		"eslint-plugin-cypress": "2.13.3",
		"eslint-plugin-import": "2.27.5",
		"eslint-plugin-prettier": "4.2.1",
		"eslint-plugin-unused-imports": "2.0.0",
		"postcss": "8.4.25",
		"prettier": "2.8.8",
		"stylelint": "15.10.1",
		"stylelint-config-clean-order": "5.0.1",
		"stylelint-config-standard-scss": "10.0.0",
		"stylelint-prettier": "3.0.0",
}

Code Snippet

Stylelint Configuration

{
	"files": ["*.css", "**/*.css"],
	"extends": ["stylelint-config-standard-scss", "stylelint-config-clean-order"],
	"plugins": ["stylelint-prettier"],
	"defaultSeverity": "warning",
	"overrides": [
		{
			"files": ["*.scss", "**/*.scss"],
			"customSyntax": "postcss-scss"
		}
	],
	"rules": {
    "prettier/prettier": true,
		"color-hex-length": "short",
		"scss/dollar-variable-empty-line-before": null
	}
}

Extension Configuration

{
  "stylelint.packageManager": "yarn",
  "stylelint.reportDescriptionlessDisables": true,
  "stylelint.reportInvalidScopeDisables": true,
  "stylelint.reportNeedlessDisables": true,
  "stylelint.snippet": ["css", "scss"],
  "stylelint.validate": ["css", "scss"],
  "[css]": {
    "editor.defaultFormatter": "stylelint.vscode-stylelint"
  },
  "[scss]": {
    "editor.defaultFormatter": "stylelint.vscode-stylelint"
  },
}

Actual Behaviour

Shows an error and does not format

Expected Behaviour

That it does not show any errors and reformat as before.

Going back to prettier version 2.8.8 fixes everything.

Likely an issue with the stylelint-prettier plugin than this extension.

@drackp2m It's now not recommended to use these plugins. Instead, you can just run Stylelint and Prettier separately.

VS Code config:

{
  "editor.formatOnSave": true,
  "editor.codeActionsOnSave": {
    "source.fixAll.stylelint": true
  },
  "stylelint.validate": ["css", "scss"],
  "editor.defaultFormatter": "esbenp.prettier-vscode"
}

Also, you don't need to use the custom syntax directly as the scss config bundles it for you:

{
	"extends": ["stylelint-config-standard-scss", "stylelint-config-clean-order"],
	"defaultSeverity": "warning",
	"rules": {
		"color-hex-length": "short",
		"scss/dollar-variable-empty-line-before": null
	}
}
