[PPR] TypeError: Response.clone: Body has already been consumed.

Testing out PPR and PFPR and it seems to be working well for the most part (nice work). However, in one of my routes I am seeing a 500 for the prefetch RSC GET request. Clicking a Link to those pages causes a full page load, but it does ultimately load the content.

⨯ TypeError: Response.clone: Body has already been consumed.

}

I'm not opening an Issue yet as I don't have a clear way to reproduce (I don't know what's different about this page from others that are working). Happy to help investigate this if you can give me some pointers on what to try / where to look. Also happy to share a Vercel preview build URL / create a Replay, if that's helpful.

Fixed in #70082 🎉

We're dealing with this error in our production build on next@14.2.9. Is the only way to resolve it by upgrading to the canary release for v15?
