The response

{
  cancelled: [],
  data: [],
  fieldErrors: [],
  error: 'No data detected. Have you used `{extended: true}` for `bodyParser`?'
}

Req.body

staff.ts (copied from example)

import db from '../../db'
import { Editor,Field,Validate,Format,Options } from "datatables.net-editor-server"
import { NextApiRequest, NextApiResponse } from "next";

export default async (req: NextApiRequest, res: NextApiResponse) => {

    That all looks fairly sensible so far. Have you done as the error message says and used the extended option for bodyParser? Can you show me that bit of the code?

    Thanks,
    Allan

    @allan
    Where should I put it ?

    I have tried

    ...
    import { NextApiRequest, NextApiResponse } from "next";
    
    export const config = {
      api: {
        bodyParser: {
          extended:true
        },
      },
    }
     
    export default async (req: NextApiRequest, res: NextApiResponse) => {
        let editor = new Editor(db as any, 'datatables_demo').fields(
    ..
    

    still not working

    I have tried both with expressJS and nextJS, apparently both of them parsing the body differently. It works fine on expresJS.

    req.body on expressJS

    {
        "data" : {
            "row_5" : {
                "DT_RowId": "row_5",
                "first_name": "Airi",
                "last_name": "Satou",
                "position": "Accountant",
                "office": "Tokyo",
                "extn": "5407",
                "age": "33",
                "salary": "162700",
                "start_date": "2008-11-28"
            }
        },                                
        "action": "remove"
    }
    

    req.body on NextJS

    {
      'data[row_5][DT_RowId]': 'row_5',
      'data[row_5][first_name]': 'Airi',
      'data[row_5][last_name]': 'Satou',
      'data[row_5][position]': 'Accountant',
      'data[row_5][office]': 'Tokyo',
      'data[row_5][extn]': '5407',
      'data[row_5][age]': '33',
      'data[row_5][salary]': '162700',
      'data[row_5][start_date]': '2008-11-28',
      action: 'remove'
    }
    

    Can you try it on NextJS ?

    I haven't used NextJS yet myself and I'm travelling at the moment so I can't experiment just now. However a quick Google suggests that many NextJS projects are built on top of Express - eg https://www.stackchief.com/blog/NextJS%20Examples%20%7C%20Express .

    Do you know if you've got express in your stack as well?

    Actually, nextjs includes its own webserver
    https://nextjs.org/docs/advanced-features/custom-server

    You can use your own server express, but it will strip away some features on the nextjs. And I prefer not doing that.
