보내주신 코드 넣어서 했는데

(index):104

Uncaught TypeError: Cannot read properties of undefined (reading 'length')

at Object.success ((index):104:38)

at c (jquery.min.js:2:28294)

at Object.fireWith [as resolveWith] (jquery.min.js:2:29039)

at l (jquery.min.js:2:79800)

at XMLHttpRequest.<anonymous> (jquery.min.js:2:82254)

이렇게 오류가 뜹니다.
