This error comes when you try to access req.headers somewhere (maybe in a middleware for your project).

When using nuxt generate, keep in mind that req & res are undefined. See https://nuxtjs.org/api#context

@atinux thanks for your reply.
you are right. But still don't understand.

I write a middleware for get user-agent, and use in layout.

export default function (context) {
  if (context.isServer) {
    let ua = context.req.headers['user-agent']
    context.app.store.state.isWX = !!(/micromessenger/.test(ua.toLowerCase()))
  }
}

I just get some info , didn't change any thing.
How can I improve the code??

[didiself]

After thinking , I try get userAgent in client.
so generate done without error.

but I think it's should running in server.

@didiself it cannot run on the server-side since no server is run when nuxt generate & no navigator is used to generate the route.
