Failed to execute 'json' on 'Request': body stream already read

[reservas-brujastower]

I am creating a project with Vercel KV, and although my current version works correctly and I can log in (both in preview and production), when creating new versions or making minor changes, I can no longer log in in preview (but I can in production). The error message that appears is:

“[SERVER] Login error: Failed to execute ‘json’ on ‘Request’: body stream already read”.

I have tried reverting to previous versions that were working fine and making slight changes that do not affect Vercel KV, but the error persists. Everything was working correctly yesterday, but today it stopped working without me making any changes.

I suspect this could be a temporary issue with Vercel and Vercel KV, but I don’t know who to report the error to or if anyone can help me. Additionally, I can log in in production, but the error only appears in the “Preview” environment before production.

Any insights or assistance would be greatly appreciated. Thank you!

It sounds like environment variables are out of sync, or like KV was enabled only for production environment
