You need to use the TypeScript version of the rule, ESLint's rules aren't aware of types

This helped me solve the issue by extending typescript-eslint.

-# .eslintsrc.js
const path = require("path")

module.exports =  {
  "root": true,
  "extends": [
    "eslint:recommended",
    "next/core-web-vitals",
    "plugin:eslint-plugin-next-on-pages/recommended",
    "plugin:tailwindcss/recommended",
    "next",
    "prettier",
    
  ],
  settings: {
    tailwindcss: {
      config: path.join(__dirname, './tailwind.config.ts'),
    },

Bigeye scad
Quick google search for how to remove no unused vars eslint should help you out
//disable…
I already know that. I asked this question to remove this warning
Bigeye scad
No, in your eslint config file
i only have this 
{
  "extends": "next/core-web-vitals",
  "rules": {
    "@next/next/no-img-element": "off"
  }
}
i dont get no-unused-vars error with this config
@Bigeye scad No, in your eslint config file
Anay-208OP
