Filling datatable with mysql in javascript

*_Expected behavior_*

Hi, I have a simple question about how to fill a datatable with data from a mysql database, using javascript (I'm working with electron js framework and mysql2 library)I know that datatable get data in JSON format or object array so: I get data from my table with a simple query, format data with mapping and get JSON. Put JSON into datatable with update statement and show datatable correctly.

*_Actual behavior_*

If I use an object array written manually it's all ok, but if I use my data getted and formatted from my database i can't show results...But with console.log() I can see data exists and seems formatted correctly.

Resources (screenshots, code snippets etc.)

// This works

const data_example_manual = [{ name : 'name', surname : 'surname', notes : 'notes',},{...},{...}];

// This doesn't works

const connection = await connectToDB('test');

const query = 'SELECT name, surname, notes FROM table';

const results = await connection.query(query);

const customJSON = results.map((row, index) => ({
  index: index + 1,
  name: row.name,
  surname: row.surname,
  notes: row.notes
}));

// This log seems to show data in right format, but when I use them datatable not show rows 
console.log(customJSON);

Thanks for your help.
