onUploadFinish error throw not being returned to client

Hi,

Not sure if I'm missing something. I tried a simple server:

`'use strict'

import {Server} from '@tus/server';
import {FileStore} from '@tus/file-store';

const host = '127.0.0.1'
const port = 1080
const server = new Server({
path: '/uploads',
datastore: new FileStore({directory: './uploads'}),
async onUploadFinish(req, res, upload) {
throw {body: 'no', status_code: 500};
return res;
}
})

server.listen({host, port})`

And when I try with a simple tus client:

`'use strict'

import * as fs from 'node:fs';
import * as tus from 'tus-js-client';

const path = './example.doc';
const file = fs.createReadStream(path);

const options = {
endpoint: 'http://127.0.0.1:1080/uploads/',
metadata: {
filename: 'example.doc',
filetype: 'application/msword',
description: 'scooby doobie doo'
},
onError (error) {
console.error('An error occurred:')
console.error(error)
process.exitCode = 1
},
onProgress (bytesUploaded, bytesTotal) {
const percentage = ((bytesUploaded / bytesTotal) * 100).toFixed(2)
console.log(bytesUploaded, bytesTotal, ${percentage}%)
},
onSuccess () {
console.log('Upload finished:', upload.url)
},
};

const upload = new tus.Upload(file, options);
upload.start();`

The upload completes without error.

node ./tus-client.js
0 3690496 0.00%
65536 3690496 1.78%
3690496 3690496 100.00%
Upload finished: http://127.0.0.1:1080/uploads/b21c2577eee60411d30b9edc01d7b4ff

Any help would be appreciated!

thanks

Start at the Server onUploadFinish entry point and trace how a thrown error is handled after the upload completes. Reproduce the behavior with the server and tus client snippets in the issue, then verify that the client receives the callback's failure response instead of a successful upload.
