Why eat the possible errors in the upload ? about next-upload

This is indeed an oversight. PRs welcome.

@TimMikeladze Actually for my use case, I think it's better to use a server action like the following:

'use server'

import { nup } from '@/app/upload/nup';

async function idExistInBucket(id: string): Promise<boolean> {
    try {
        await nup.init();
        await nup.getAsset({ id });
    }
    catch (error) {
        return false;
    }

    return true;
}

export async function idsExistInBucket(ids: string[]): Promise<Map<string, boolean>> {
    const resultMap = new Map<string, boolean>();
    const promises = ids.map(async id => {
        const exists = await idExistInBucket(id);
        resultMap.set(id, exists);
    });

    await Promise.all(promises);

    return resultMap;
}

With this server action, I can do the existence verification before uploading files in the client, avoiding upload requests for already existent files:

    const uploadFiles = async () => {
        const orderAndFilesArray = await cacheOperator.getOrderAndFilesArray(orderIds);

        await Promise.all(
            orderAndFilesArray.map(async (orderAndFiles) => {
                const files = orderAndFiles.files.map((file) => {
                    return { id: `${file.imageId}`, file: blobToFile(arrayBufferToBlob(file.file, file.type), `${file.imageId}`) };
                });
                const filesIds = files.map(file => file.id);
                const resultMap = await idsExistInBucket(filesIds);
                const uploadPromises = [];

                for (const file of files) {
                    if (!resultMap.get(file.id)) {
                        uploadPromises.push(nup.upload(file));
                    }
                }

                await Promise.all(uploadPromises);
            })
        );
    };

This not only ensures error prevention but also idempotence. So, I'm retreating on my PR suggestion for now. But how do you think it should be done ? My idea was just adding a throw("Generic error") inside the upload's catch block, in the file src/react/useNextUpload.tsx.
