Something wrong when rollup.config.js export an array

[DeepenLau]

// rollup.config.js

  }

  return config
}

const configs = [
  setConfig({
    input: './src/auth/main.js',
    output: {
      minifyFilename: './dist/auth/index.min.[hash].js',
      filename: './dist/auth/index.js'
    },
    html: {
      template: './src/auth/index.html',
      filename: 'auth/index.html',
    }
  }),
  setConfig({
    input: './src/home/main.js',
    output: {
      minifyFilename: './dist/home/index.min.[hash].js',
      filename: './dist/home/index.js'
    },
    html: {
      template: './src/home/index.html',
      filename: 'home/index.html',
    }
  })
]

export default configs

I got this in auth/index.html

and i got this in home/index.html

By the way, the path is not my expectation
