Preview not working with route resolver

[juliandreas]

I have an issue where preview works fine on routes that's in the link-resolver, but routes that goes through the Route resolver does not work and I get redirected to the 404-page.

Is there anything I can do to fix this, or is it a Beta issue?

link-resolver.js

export default function(doc) {
  if (doc.isBroken) {
    return `/${doc.lang}/404`;
  }
  if (doc.type === 'homepage' && doc.lang === 'sv') {
    return '/';
  }
  if (doc.type === 'homepage' && doc.lang !== 'sv') {
    return `/${doc.lang}`;
  }
  if (doc.type === 'page') {
    return `/${doc.lang}/${doc.uid}`;
  }

  return `/${doc.lang}/404`;
}

nuxt.config.js

prismic: {
    endpoint: process.env.PRISMIC_URL,
    apiOptions: {
      accessToken: process.env.PRISMIC_API_KEY,
      routes: [
        {
          type: 'post',
          path: '/:lang/:category/:uid',
          resolvers: {
            category: 'category'
          }
        }
      ]
    },
    disableGenerator: true
  }

Hello @juliandreas, thanks for reaching out.

Your setup is correct. Is the page working in dev mode?
Maybe there's something missing in the file structure, could you share this with us?

The page is working in both dev and production, it's the preview mode that is not working.
Do you mean if the preview is working in development? Because I have no idea how to check that.

@juliandreas Thanks for sending over the details of your project. I will escalate this case to the relevant team and come back when we reproduce the use case and have more information.
