Rollup + Typescript + ESLint wrong warning

I created a project using Rollup which use Typescript and ESLint with the typescript-eslint plugin and it seems that ESLint is executed on compiled code.

Here is my Rollup config :

export default commandLineArgs => {
  const serving = commandLineArgs.configServe === true;

  return {
    input: 'src/main.ts',
    output: {
      file: pkg.main,
      format: 'umd',
      name: 'bot',
      sourcemap: !isProduction
    },
    plugins: [
      eslint({ include: ['src/**/*.js', 'src/**/*.ts'] }),
      nodeResolve(),
      commonjs(),
      typescript({ sourceMap: !isProduction, inlineSources: !isProduction }),
      replace({
        'process.env.NODE_ENV': JSON.stringify(isProduction ? 'production' : 'development')
      }),
      scss({
        includePaths: ['node_modules/'],
        outputStyle: isProduction ? 'compressed' : 'expanded'
      }),
      html({ include: 'src/**/*.html' }), // to allow import of html files (for templating)
      image(), // to allow import of image files
      isProduction && terser(),
      isProduction && filesize(),
      serving && serve({
        open: true,
        openPage: '/index.html',
        contentBase: ['demo', 'dist'],
      })
    ]
  }
}

Here is my main.ts :

import './styles/app.scss';

import ChatUI from './ui';
import Chat from './chat';

export default async function init(target: HTMLDivElement): Promise<Chat> {
  const ui = new ChatUI(target);
  const chat = new Chat(ui);

  return chat;
}

And this is what ESLint logs :

.../src/main.ts
4:16  warning  Missing return type on function    @typescript-eslint/explicit-module-boundary-types
4:36  warning  Argument 'target' should be typed  @typescript-eslint/explicit-module-boundary-types

As you can see, both line numbers and errors are wrong, as if it use the generated js file rather than the ts source. What is the problem here ?
