I’ve installed typescript-eslint and it works great when I have the following config:

import eslint from "@eslint/js";
import tseslint from "typescript-eslint";

export default tseslint.config(
  eslint.configs.recommended,
  ...tseslint.configs.recommended
);

However, when I add a new rule to the config, it stops working entirely:

import eslint from "@eslint/js";
import tseslint from "typescript-eslint";

export default tseslint.config(
  eslint.configs.recommended,
  ...tseslint.configs.recommended,
  {
    rules: {
      "@typescript-eslint/no-floating-promises": "error",
    },
  }
);

I’m literally just following their docs. I have no clue why this is not working.
