Possible fix
You need to fix the code from line 198 on.
Current code:
if (index === 0 && !element.parentElement.id) {
let tmpId = allElements[index + 1].parentElement.id;
let regex = /tt_content-[0-9]+/;
let id = tmpId.replace(regex, 'tt_content-0');
element.parentElement.setAttribute('id', id);
}
This is our quickfix:
if (index === 0 && (!element.parentElement || !element.parentElement.id)) {
let tmpId = allElements[index + 1]?.parentElement?.id || 'tt_content-0';
let regex = /tt_content-[0-9]+/;
let id = tmpId.replace(regex, 'tt_content-0');
element.parentElement.setAttribute('id', id);
} else {
element.setAttribute('id', id); // Assign to element if no parent exists
}
