The incoming traces from the middleware don't have any children; instead, they are reported separately. What am I doing wrong? Ideally, the traces should be structured well, linked to each other, and the parent ID should be configured correctly, right?

instrumentation.ts

import { PrismaInstrumentation } from "@prisma/instrumentation";
import { registerOTel } from "@vercel/otel";

export function register() {
  registerOTel({
    serviceName: "nextjs",
    instrumentations: [new PrismaInstrumentation({ middleware: true })],
  });
}
