'deprecation/deprecation': You have used a rule which requires parserServices to be generated.

This error pops up when I try and use projectService configurations in my @typescript-eslint/parser

{
  files: ["**/*.ts", "**/*.tsx"],
  parser: "@typescript-eslint/parser",
  parserOptions: {
    ecmaVersion: "latest",
    projectService: {
      defaultProject: "./tsconfig.json",
    },
    tsconfigRootDir: __dirname,
  }
}

Not sure if anyone has run into this or found a solution?
