Compile js in tsconfig

I am working on a project that creates a web extension. Normally, I write my code with ts.
I want to add my js file in my project. I am getting an error “only amd and system modules aare supported alongside –outfile”

{
  "compilerOptions": {
    "jsx": "react",
    "module": "es6",
    "target": "es6",
    "moduleResolution": "node",
    "esModuleInterop": true,
    "outDir": "./dist",
    "allowJs": true,

    "outFile": "./dist/background.js"
  },
  "include": ["src/**/.ts", "src/**/*.tsx"],
  "exclude": ["node_modules"]
}
