guess: TypeError: Cannot read property 'eagerRoutes' of undefined

Can´t read property ‘eagerRoutes’ of undefined

My extend.webpack.config.js is like below:

const { GuessPlugin } = require('guess-webpack');
const { parseRoutes } = require('guess-parser');

module.exports = {
  plugins: [
    new GuessPlugin({
      GA: '<GAV Id>', 
      runtime: {
        delegate: false
      },
      routeProvider() {
        return parseRoutes('.');
      }
    })
  ]
};

But I get this error when I run the ng build --prod command.

Unfortunately, there’s nothing I can do at this point. You can generate JWT tokens and provide them to Guess.js in a similar way I did here.

Not sure what the text says. Would you translate?

Fixed in https://github.com/guess-js/guess/pull/312. Let me know when you verify so I can release the fix.

Guess.js gets confused because you don’t have route declarations in about-routing.module.ts, which makes sense, but still the failure should not happen.

Until I push a fix, you can workaround the problem by replacing your about-routing.module.ts with:

import { NgModule, Component } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';

@Component({
  selector: 'foo',
  template: 'bar'
})
export class AboutComponent {}


const routes: Routes = [{
  path: '',
  pathMatch: 'full',
  component: AboutComponent
}];

@NgModule({
  imports: [RouterModule.forChild(routes)],
  exports: [RouterModule]
})
export class AboutRoutingModule { }

Just found the public repo in your account and reproduced the problem. I’ll see what I can find.
