Hi, when I run tsc tsconfig.json, I have an error TS2574 in unified module.
node_modules/unified/index.d.ts:590:47 - error TS2574: A rest element type must be an array type.

here is what in tsconfig.json

{
  "extends": "../tsconfig.json",
  "compilerOptions": {
    "module": "esnext",
    "lib": ["es2015", "es2017", "dom", "WebWorker.ImportScripts"],
    "target": "es5",
    "baseUrl": "src",
    "allowSyntheticDefaultImports": true,
    "noEmit": true,
    "removeComments": false,
    "downlevelIteration": true
  },
  "exclude": ["node_modules"],
  "include": ["src/**/*", "scripts/**/*.ts"]
}

recently for @types/react I am using the version 17.0.5 . I have tried to upgrade and downgrade the version but I still have the same error. and for unified, I have version ^10.0.0

• What TS version?
• Are you writing your own plugins?
