JSON is added to web page but Datatables don't recognize it, only table hand made in HTML

fetch("searchy.json")
.then(function (response) {
return response.json();
})
.then(function (data) {
appendJson(data);
})
.catch(function (err) {
console.log(err);
});

I use this fetch to take my 43214 objects long json... it looks good on my browser.

The very first row is repeated with the second because i typed it myself in my html.

This is what my appendJson function does:
const appendJson = (data) => {
//I put j < 42 because I'm debugging and testing and having 43214 lasts way longer
for (let j = 0; j < 42; j++) {
const tr = document.createElement("tr");

const exploit = document.createElement("td");
const edbid = document.createElement("td");
const fecha = document.createElement("td");
const autor = document.createElement("td");
const tipo = document.createElement("td");
const plataforma = document.createElement("td");
const path = document.createElement("td");

const table = document.getElementById("bodyTable");
exploit.textContent = `${data["RESULTS_EXPLOIT"][j].Title}`;
edbid.textContent = `${data["RESULTS_EXPLOIT"][j]["EDB-ID"]}`;
fecha.textContent = `${data["RESULTS_EXPLOIT"][j].Date}`;
autor.textContent = `${data["RESULTS_EXPLOIT"][j].Author}`;
tipo.textContent = `${data["RESULTS_EXPLOIT"][j].Type}`;
plataforma.textContent = `${data["RESULTS_EXPLOIT"][j].Platform}`;
path.textContent = `${data["RESULTS_EXPLOIT"][j].Path}`;

table.appendChild(tr);
tr.appendChild(exploit);
tr.appendChild(edbid);
tr.appendChild(fecha);
tr.appendChild(autor);
tr.appendChild(tipo);
tr.appendChild(plataforma);
tr.appendChild(path);

}
};

And this is my Datatable jQuery:
$(document).ready(function() {

$('#jsonTable').DataTable({

"lengthMenu": "Mostrar MENU registros",
"zeroRecords": "No se encontraron resultados",

});
});
