Unable to prerender all routes!

Hello everyone, everything good? I am in trouble, when I run the command npm run build this message appears:

[prerender-spa-plugin] Unable to prerender all routes! (node:24767) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 3): Error: Protocol error (Page.navigate): Cannot navigate to invalid URL undefined (node:24767) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

But my app has a protection (main.js) that depends on a choice to continue.

router.beforeEach((to, from, next) => {
  // check if the user item is already set
  if (to.path !== '/painel' && !window.sessionStorage.getItem('programaId')) {
    next('painel')
  } else {
    next()
  }
})

My question is: is there a way to trigger prerender after that choice?

I put headless: false, opened the Chromium, but I could not identify what it was, I went in the config I took the event to run after the element exists, then finished the construction. I opened the dist folder and had a ‘/panel’ index, even though it ran the other routes, it did not work the way I imagined it to. Thanks for the effort!

You could use renderAfterDocumentEvent and dispatch an event after the relevant components mount. However, it would appear your config contains an undefined value as a route, which is causing the error here.
