尝试更新表-错误：未处理的承诺拒绝node.js

Question

启动应用程序时，我试图用哈希密码更新用户。所以我在app.js：

中写了这个

try {
  bcrypt.hash("ADMIN", saltRounds, async function(err, hash) {
    queryUpdate = await Utilisateur.query().patch({
        MOTPASS: hash
    }).where('NOGENE', 4219)
    .catch(console.log('err'));
 });
} catch (err) {
  errorDbHandler.sendErrorHttp(err, res);
}

我收到此错误：

(node:6800) UnhandledPromiseRejectionWarning: TypeError: Utilisateur.query is not a function
    at D:\Project\***\backend\app.js:48:37
(node:6800) 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:6800) [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.

使用此代码捕获错误：

try {
  bcrypt.hash("ADMIN", saltRounds, async function(err, hash) {
    try {
      queryUpdate = await Utilisateur.query().patch({
        MOTPASS: hash
      }).where('NOGENE', 4219);
    } catch (e) {
      console.log(e);
    }
 });
} catch (err) {
  errorDbHandler.sendErrorHttp(err, res);
}

您试图将“ then（）。catch（）”与“ await”混合使用，这是行不通的。
