How to fix this?

sry, I tried it and found that I was wrong with the configuration.

// babel.config.js
module.exports = {
  presets: [
    ['@vue/app', {
      polyfills: [
        'es6.promise',
        'es6.object.assign',
        'es6.object.keys',
        'es6.array.includes'
      ]
    }
    ]
  ]
}

When I deleted some configurations, the build was successful.

// babel.config.js
module.exports = {
  presets: [
    ['@vue/app', {
      polyfills: [
        'es6.promise'
      ]
    }
    ]
  ]
}

The question now is how to configure polyfills?

es6.array.includes -> es7.array.includes
