Server error: Failed to parse postponed state Error: unexpected end of file at ignore-listed frames { errno: -5, code: ‘Z_BUF_ERROR’ }

Browser console error: Error: Connection closed. at eu (deeedf44c97ddc53.js:1:27846) at t (deeedf44c97ddc53.js:1:28201)

Additional context

Additional context The error only occurs on deployment, not in local development Removing all logic from the component doesn’t fix the issue The error appears to be related to corrupted/incomplete compressed data in the postponed state that PPR generates

Environment Next.js version: 16.0.4

Happens only with el locale set and not with en which is weird. Tried to remove all logic and left the page and the parent layout empty and still got same error
