Does this happen with a browser or just Postman? That content is the React Server Components streaming updates

It happens in both scenarios, I noticed this bug because I kept downloading stuff when I’m trying to access the site, then I tested with postman.

Could you try updating the runtime to 4.29.4. This is a new version which supports appDir in the normal release, though it isn't auto-installed yet.

Updated to 4.29.4, the issue still exists.

I think I have a diagnosis for this. I'm going to rename this and merge with an issue that's kind've the opposite, but a manifestation of the same problem.
