Javascript 如何在Svelte中从一个codec函数中调用error()

从async函数内部使用error()时，脚本崩溃，并显示以下错误.

使用import { error } from '@sveltejs/kit';

如何在Svelte中从async函数中调用error()？

node:internal/process/promises:289
            triggerUncaughtException(err, true /* fromPromise */);
            ^

[UnhandledPromiseRejection: 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(). The promise rejected with the reason "#<Redirect>".] {
  code: 'ERR_UNHANDLED_REJECTION'
}

Node.js v20.11.0

Code Minimum Sample Code Minimum Sample Code Minimum Sample Src/routes/+page.svelte(基本加载URL)

<script lang="ts">
    import { error } from '@sveltejs/kit';

    const tst = async() => error( 400, 'My error message' );

    tst();
</script>

Case 2此代码在JS控制台中产生一个相似错误(未捕获(In Promise))

<script lang="ts">
    import { error } from '@sveltejs/kit';
    import { onMount } from 'svelte';

    onMount( async function() 
    {
        error( 400, 'My error message' );
    } ); 
</script>

从函数中删除异步确实解决了这个问题，但我想使用异步.

我还希望避免在每个异步函数调用中使用try .. catch.
