Nuxt asyncData Missing Data in Full Static Generate

When using asyncData and generate full static pages, I found some generated pages (npm run generate) have missing data loaded via asyncData.

• This problem doesn't appear in development, only in npm run generate
• The generated static pages should have embed the data loaded via asyncData in the html files, but somehow those data are missing.

The culprit is generate.routes in nuxt.config.js, when you have path which didn't start with /.

export default {  generate: {    routes: [      '/',      '/page/2',      'page/3' // this page will have missing data, as the path doesn't start with /    ]  }}

NOTE: Tested on Nuxt v2.14.6
