google sheets, apps script parsehtml error - google-apps-script

Question

this is the complete code,
function extractData() {
var url = "https://www.theopenalliance.com/teams/2023/";
var html = UrlFetchApp.fetch(url).getContentText();
var data = parseHtml(html);
var sheet = SpreadsheetApp.getActiveSheet();
sheet.clearContents();
if (data.length > 0) {
sheet.getRange(1, 1, data.length, data[0].length).setValues(data);
for (var i = 0; i < data.length; i++) {
for (var j = 0; j < data[i].length; j++) {
if (data[i][j].indexOf("http") === 0) {
var button = sheet.getRange(i + 1, j + 1).attachButton({
text: "Link",
url: data[i][j]
});
}
}
}
}
}
function parseHtml(html) {
var startIndex = html.indexOf("<tbody>");
var endIndex = html.indexOf("</tbody>");
var table = html.substring(startIndex, endIndex);
var rows = table.split("<tr>");
var data = [];
for (var i = 1; i < rows.length; i++) {
var cells = rows[i].split("<td");
var row = [];
for (var j = 1; j < cells.length; j++) {
var cell = cells[j];
var linkStartIndex = cell.indexOf("href=");
if (linkStartIndex !== -1) {
var linkEndIndex = cell.indexOf("class");
var link = cell.substring(linkStartIndex + 6, linkEndIndex - 2);
row.push(link);
} else {
row.push(cell.substring(cell.indexOf(">") + 1, cell.indexOf("</td>")));
}
}
data.push(row);
}
return data;
}
however function parseHtml(html) gives an error with this line
var startIndex = html.indexOf("<tbody>");
Anyone has any suggestions? i'm trying to copy and paste tables from the link to a google sheets.
i expected to see every teams numbers and other values (Public links, location etc) in google sheets but nothing shows up. Also i was expecting to see buttons that had links attached to them if the buttons exists, such as github, photos etc. Please check the link and im sure you will have a better idea of im trying to tell. Also please help me fix the code, if possible, copy and edit the code than repost it, i would greatly appreciate it

In your situation, how about using Sheets API? Because I thought that the HTML parser of Sheets API is useful for your situation. When Sheets API is used for your URL, how about the following sample script?
Sample script:
Before you use this script, please enable Sheets API at Advanced Google services.
function myFunction() {
const url = "https://www.theopenalliance.com/teams/2023/"; // This is from your script.
const html = UrlFetchApp.fetch(url).getContentText();
const table = html.match(/<table[\s\S\w]+?<\/table>/);
if (!table) {
throw new Error("Table was not found.");
}
const ss = SpreadsheetApp.getActiveSpreadsheet();
const sheet = ss.getActiveSheet().clearContents();
SpreadsheetApp.flush();
const requests = { requests: [{ pasteData: { html: true, data: table[0], coordinate: { sheetId: sheet.getSheetId() } } }] };
Sheets.Spreadsheets.batchUpdate(requests, ss.getId());
}
When this script is run, a table is retrieved from the URL and put it into the active sheet.
