const buffer = await renderToBuffer(
        <OtpsPdf event={eventFormatted} otps={data} />
      );

      return new Response(buffer, {
        headers: {
          "Content-Type": "application/pdf",
          "Content-Disposition": `attachment; filename="Codici: ${event.name}.pdf"`,
        },
      });

Why this code in a NextJS GET function return an Internal Server error in production (I have deployed on Vercel)

In development everthing works fine.

Thank you
