i´m currently new to sheets coding, i´ve been following this tutorial in order to create a userform, the problem is when i get to approximately 19:03 of the video, my view of "Search" tab doesn´t seem to work, below are my codes:
https://www.youtube.com/watch?v=6zFowiTNhqI
loadForm.gs
function loadMainForm() {
const htmlServ = HtmlService.createTemplateFromFile("main");
const html = htmlServ.evaluate();
html.setWidth(850).setHeight(600);
const ui = SpreadsheetApp.getUi();
ui.showModalDialog(html, "Editar informações dos prescritores")
}
function createMenu(){
const ui = SpreadsheetApp.getUi();
const menu = ui.createMenu("Custom Menu");
menu.addItem("Open Form", "loadMainForm");
menu.addToUi();
}
function onOpen(){
createMenu();
}
search.html
<h1>Search</h1>
addcustomers.html
<h1>Add Customers</h1>
main.html
<!doctype html>

function loadSearchView(){
google.script.run.withSuccessHandler(function(html){
document.getElementById("app").innerHTML = html;
}).loadSearchView();
}
document.getElementById("search-link").addEventListener("click",loadPartialHTML);
</script>
</body>
</html>
loadPartials.gs
function loadPartialHTML_(partial) {
const htmlServ = HtmlService.createTemplateFromFile(partial);
return htmlServ.evaluate().getContent();
}
function loadSearchView(){
return loadPartialHTML_("search");
}
function loadAddCustomersView(){
return loadPartialHTML_("addcustomers");
}
I´ve already tried rewriting the code 3 times, and nothing seems to work, when i open the console, an error appears as the following image

If someone could please help me figure out what I did wrong, I would be very grateful
