Hi guys, I am having problems parsing theb json body, it works if parsed manually but is it possible to parse it automatically?

If I use req.body directly:

The output of req.body is: ReadableStream { locked: false, state: 'readable', supportsBYOB: false }
.
But if I parse it manually it works properly:

import { NextApiRequest, NextApiResponse } from "next";

export default async function handler(
  req: NextApiRequest, res: NextApiResponse
) {
  try {
    const isStream = typeof req.body === 'object' && req.body?.constructor?.name === 'ReadableStream';
    let parsedBody = req.body;

    if (isStream) {
      const chunks = [];
      for await (const chunk of req.body) {
        chunks.push(chunk);
      }

      const rawBody = Buffer.concat(chunks).toString('utf-8');
      parsedBody = JSON.parse(rawBody);
    }

    // Extract stripeId and userId from parsed body
    const { stripeId, userId } = parsedBody;

    if (!stripeId) {
      return res.status(400).json({ error: "stripeId is missing!" });
    }

    if (!userId) {
      return res.status(400).json({ error: "userId is missing!" });
    }

    return res.status(200).json({ 
      stripeId,
      userId,
    });

  } catch (error) {
    console.error("Handler error:", error);
    return res.status(500).json({ error: error.toString() });
  }
}
