TypeError: The "payload argument must be of type object. Received null at log"

Hi there, I have faced an error while creating a project. This is a file in the route.js. I am using prisma database to connect. I have checked all those npx prisma migrate and they still came out with this error.

Here is my code: `import db from "@/lib/db"; import { NextResponse } from "next/server";

export async function POST(request) { try { // Read and parse request body let body; try { body = await request.json(); } catch (err) { console.error("Invalid JSON received:", err); return NextResponse.json( { message: "Invalid JSON format" }, { status: 400 } ); }

if (!body || Object.keys(body).length === 0) {
  return NextResponse.json(
    { message: "Request body cannot be empty" },
    { status: 400 }
  );
}

// Validate required fields
const requiredFields = ["name", "quantity", "sellingPrice", "buyingPrice"];
for (const field of requiredFields) {
  if (!body[field]) {
    return NextResponse.json(
      { message: `Missing required field: ${field}` },
      { status: 400 }
    );
  }
}

// Log request body for debugging
console.log("Received body:", body);

// Extract fields with safe default values
const {
  name,
  description = "",
  categoryId = null,
  sku = "",
  barcode = "",
  quantity,
  unitId = null,
  brandId = null,
  sellingPrice,
  buyingPrice,
  supplierId = null,
  reOrderPoint = null,
  location = "",
  imageURL = "",
  weight = null,
  dimensions = "",
  taxRate = null,
  notes = "",
} = body;

// Convert numeric fields safely
const numericFields = {
  quantity: isNaN(parseInt(quantity, 10)) ? 0 : parseInt(quantity, 10),
  sellingPrice: isNaN(parseFloat(sellingPrice))
    ? 0
    : parseFloat(sellingPrice),
  buyingPrice: isNaN(parseFloat(buyingPrice)) ? 0 : parseFloat(buyingPrice),
  weight: weight ? parseFloat(weight) : null,
  taxRate: taxRate ? parseFloat(taxRate) : null,
  reOrderPoint: reOrderPoint ? parseInt(reOrderPoint, 10) : null,
};

// Insert into the database
const newItem = await db.item.create({
  data: {
    name,
    description,
    categoryId,
    sku,
    barcode,
    unitId,
    brandId,
    supplierId,
    location: location || null,
    imageURL: imageURL || null,
    dimensions,
    notes,
    ...numericFields,
  },
});

console.log("Created item:", newItem);

if (!newItem) {
  throw new Error("Database returned null, possible insertion failure");
}

return NextResponse.json(newItem, { status: 201 });

} catch (error) { console.error("Error creating item:", error); return NextResponse.json( { message: "Failed to create item", error: error.message }, { status: 500 } ); } }

export async function GET(request) { try { const items = await db.item.findMany({ orderBy: { createdAt: "desc" }, }); return NextResponse.json(items); } catch (error) { console.error("Error fetching items:", error); return NextResponse.json( { message: "Failed to fetch items", error: error.message }, { status: 400 } ); } } `Please help me ASAP. Thank you everyone!
