在输入'npm start'而不是在终端上获得QR码后，我得到'UnhandledPromiseRejectionWarning'错误。有人能帮我解决这个问题吗?我是初学者，所以我不知道显示错误的含义

(node:3460) 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: 1)
(node:3460) [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.

我认为你应该把你的Node版本升级到大于14的任何版本。
