Why do I get '2 arguments required, but only 1 was passed.' when trying to compile my Sass template?

Question

I get the below error while building my project

SassError: 2 arguments required, but only 1 was passed.
    width: rem(300);
           ^^^^^^^^

Below is my package.json

{
  "name": "test",
  "version": "3.0.0",
  "private": true,
  "scripts": {
   
  },
  "devDependencies": {
    "mini-css-extract-plugin": "^2.4.2",
    "node-sass": "^6.0.1",
    "postcss": "^8.3.9",
    "postcss-loader": "^6.2.0",
    "postcss-preset-env": "^6.7.0",
    "sass": "^1.3",
    "sass-loader": "^12.1.0"
  },
  "dependencies": {
    "grunt-sass": "^3.1.0"
  }

}

What is the issue?

Ran into the same problem today, I had "sass": "^1.26.5" in my package.json.

sass got updated yesterday to 1.65.1, your build should work with 1.64.2 https://www.npmjs.com/package/sass/v/1.65.1?activeTab=versions I got that problem due to another dependency I have no control over, so changing sass version was the only option for now. But if you used rem() in your own code, go for Ali Klein's answer.
