I am trying to insert data into a table but i am getting this Error: ER_BAD_NULL_ERROR: column 'name' cannot be null

I am using node js, express and mysql. My goal in to insert data into a table called sbmtidea, but when i try to execute the code i am getting

undefined undefined undefined undefined
{ name: undefined,
  email: undefined,
  password: undefined,
  phone: undefined }
{ Error: ER_BAD_NULL_ERROR: column 'name' cannot be null

I don't have any column called name in this table. The column name is in another table. I checked for auto increments. But that doesn't work either. I think i am not being directed to this table.

var express = require('express');
var router = express.Router();
var mysql =  require('mysql');

var connection = mysql.createConnection({
      host: 'localhost',
      user: 'root',
      password: '',
      database:'backend',
})

/* our backend endpoint to check for users in the database */
router.post('/', function(req, res, next) {
        console.log(' ');
        var idea_group = req.body.idea_group;
        var idea_category = req.body.idea_category;
        var idea_title = req.body.idea_title;
        var idea_detail = req.body.idea_detail;
        console.log(idea_group,idea_category,idea_title,idea_detail);

        var submitidea  = {idea_group:idea_group,idea_category:idea_category,idea_title :idea_title,idea_detail: idea_detail};
        connection.query("INSERT INTO sbmtidea set ?",submitidea,function(err,row,fields){
          if (err) console.log(err);
          });
  });

module.exports = router;

This is my react native code:

constructor(props,context){
        super(props,context);
        this.state = {
        idea_group: '',
        idea_category: '',
        idea_title:'',
        idea_detail:'',
        };
        console.log();
  }

  submit = () => {
        fetch('http://192.168.0.20:3000/submit_idea', {
         method : 'POST',
              headers: {
              'Accept': 'application/json',
              'Content-type': 'application/json',
              },
              body: JSON.stringify({
              idea_group: this.state.idea_group,
              idea_category: this.state.idea_category,
              idea_title: this.state.idea_title,
              idea_detail: this.state.idea_detail,
              })
        })
        .then((response) => response.json())
        .then((res) => {

                if(res.success=== true){
                  var idea_group= res.message;

                     AsyncStorage.setItem('idea_title',idea_title);
                     Actions.Ideas();}
                     else {
                    alert(res.message);
                }
        })
        .done();
  }

Please help...
