I am following this tutorial:

My code is:

import clientPromise from "../lib/mongodb";

export default async (req, res) => {
    try {
        const client = await clientPromise;
        const db = client.db("Reports");

        const collection = await db
        .collection("Reports")
 
        const report = await db
            .collection("Reports")
            .find({})
            .toArray()

        res.json(report);
    } catch (e) {
        console.error(e);
    }
};

In my code the report after .toArray() returns my data within an array. However, I get this error:

TypeError: Cannot read properties of undefined (reading 'json')

It seems the data comes through to the array but then there is an issue returning it as json.

NextJS made an update on this, you should return your response like so:

return new Response(JSON.stringify({report : report}), { status: 200 })

Update your code as below, it should work.

import clientPromise from "../lib/mongodb";

export const GET = async (res, req) =>{
    try {
        const client = await clientPromise;
        const db = client.db("Reports");

        const collection = await db
        .collection("Reports")
 
        const report = await db
            .collection("Reports")
            .find({})
            .toArray()

 return new Response(JSON.stringify({report : report}), { status: 200 })

    } catch (e) {
        console.error(e);
    }
};

Let me know if this is helpful.
