[Bug]: Invalid URL error when handling rewrite

[chrishannaby]

Steps to reproduce

A customer forked the zones example from Next.js which uses rewrites to stitch together multiple micro-sites into a single site using the following config:

module.exports = {
  async rewrites() {
    return [
      {
        source: "/blog",
        destination: "https://with-zones-blog.netlify.app/blog",
      },
      {
        source: "/blog/:path*",
        destination: "https://with-zones-blog.netlify.app/blog/:path*",
      },
    ];
  },
};

This example is deployed at https://silly-edison-c456ac.netlify.app if you navigate to https://silly-edison-c456ac.netlify.app/blog you will see the following error:

{"errorType":"TypeError","errorMessage":"Invalid URL: https,http://with-zones-blog.netlify.app/blog","trace":["TypeError [ERR_INVALID_URL]: Invalid URL: https,http://with-zones-blog.netlify.app/blog","    at onParseError (internal/url.js:258:9)","    at new URL (internal/url.js:334:5)","    at new URL (internal/url.js:331:22)","    at Runtime.handler (/var/task/.netlify/functions-internal/___netlify-handler/___netlify-handler.js:137:22)","    at Runtime.handleOnce (/var/runtime/Runtime.js:66:25)"]}

I am having the same problem. @chrishannaby Did you you found any solution for this so far?

[chrishannaby]

There have been significant changes in the plugin since I reported this issue but I have not validated whether they fixed this for me yet. Can you share more details on your issue @k88manish ? Site URL etc

[k88manish]

I tried to use the rewrite on my job on an internal site. So I couldn't share that but I will try it on something on my GitHub but the problem is very same even with latest plugin version

[pdpwebsecurify]

it is definitely not fixed. Also surprising this is still an issue.

@chrishannaby I've deployed the two sites (home and blog) in the example repo you supplied, and I can confirm that the blog shows up properly without error. The only changes I made were updating the next-runtime version to @netlify/[email protected]

home site: https://zones-home-test.netlify.app/

Closing as this appears to be resolved.
