Node.js – Typescript eslint – Missing file extension “ts” import/extensions

I have a simple Node/Express app made with Typescript.
And eslint give me the error

Missing file extension "ts" for "./lib/env" import/extensions

Here is my .eslintrc file

    {
  "extends": [
    "airbnb",
    "plugin:@typescript-eslint/recommended",
    "prettier",
    "prettier/react",
    "plugin:import/errors",
    "plugin:import/warnings",
    "plugin:import/typescript"
  ],
  "parser": "@typescript-eslint/parser",
  "plugins": ["@typescript-eslint", "prettier", "import"],
  "settings": {
    "import/extensions": [".js", ".jsx", ".ts", ".tsx"],
    "import/parsers": {
      "@typescript-eslint/parser": [".ts", ".tsx"]
    },
    "import/resolver": {
      "typescript": {
        "directory": "./tsconfig.json"
      },
      "node": {
        "extensions": [".js", ".jsx", ".ts", ".tsx"]
      }
    }
  },
  "rules": {
    "@typescript-eslint/indent": [2, 2],
    "no-console": "off",
    "import/no-unresolved": [2, { "commonjs": true, "amd": true }],
    "import/named": 2,
    "import/namespace": 2,
    "import/default": 2,
    "import/export": 2
  }
}

I have installed eslint-plugin-import & eslint-import-resolver-typescript.
And I cannot figure out why, I got that error.
