Promise error가 계속 발생되는데 구글링해도 답을 모르겠어요...

UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 2)

(node:5538) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

따라 작성을 했는데. 이런 에러가 뜨네요..

구글링을 해도 답이 안나와서요 ㅜ

try catch를 작성해야하는걸까요...?

혹시 이번 강의 코드는 저장된 곳 없으신가요?
