adding onUploadProgress makes the api failed

[nhridoy]

I am trying to upload to s3 using pre-signed url. Here is the code for that:

const handleImageChange = async (e: React.ChangeEvent<HTMLInputElement>) => {
    try {
      // Get presigned URL from the server
      const file = e.target.files?.[0];

      if (!file) {
        toast.error("No file selected");
        return;
      }
      const formData = new FormData();

      formData.append("file_name", file.name);
      formData.append("file_type", file.type);
      formData.append("file_size", file.size.toString());

      // Get presigned URL from the server
      const presignedUrlResponse = await apiClient<PresignedUrlType>(
        `/api/proxy/options/generate-presigned-url`,
        { method: "post", body: formData }
      );

      if (presignedUrlResponse.status !== 200) {
        toast.error("Failed to get presigned URL");
        return;
      }

      const presignedUrlData = await presignedUrlResponse.json();
      const presignedUrl = presignedUrlData.data.presigned_url;

      // Upload the file to the presigned URL
      const uploadResponse = await ky.put(presignedUrl, {
        body: file,
      });

    } catch (error) {
      console.error((error as Error).message);
    }
  };

And as expected it works fine. But when I am adding onUploadProgress it is failing to upload:

const handleImageChange = async (e: React.ChangeEvent<HTMLInputElement>) => {
    try {
      // Get presigned URL from the server
      const file = e.target.files?.[0];

      if (!file) {
        toast.error("No file selected");
        return;
      }
      const formData = new FormData();

      formData.append("file_name", file.name);
      formData.append("file_type", file.type);
      formData.append("file_size", file.size.toString());

      // Get presigned URL from the server
      const presignedUrlResponse = await apiClient<PresignedUrlType>(
        `/api/proxy/options/generate-presigned-url`,
        { method: "post", body: formData }
      );

      if (presignedUrlResponse.status !== 200) {
        toast.error("Failed to get presigned URL");
        return;
      }

      const presignedUrlData = await presignedUrlResponse.json();
      const presignedUrl = presignedUrlData.data.presigned_url;

      // Upload the file to the presigned URL
      const uploadResponse = await ky.put(presignedUrl, {
        body: file,
        onUploadProgress: (progress, chunk) => {
          // Example output:
          // `0% - 0 of 1271 bytes`
          // `100% - 1271 of 1271 bytes`
          console.log(
            `${progress.percent * 100}% - ${progress.transferredBytes} of ${
              progress.totalBytes
            } bytes`
          );
        },
      });

    } catch (error) {
      console.error((error as Error).message);
    }
  };

Here is the full log:

Also the upload progress it is logging is fake:

99% - 30627 of 30627 bytes
100% - 30627 of 30627 bytes

Can you use the network tab to show us the request headers, both with and without onUploadProgress?

Without onUploadProgress:

With onUploadProgress:

Thanks, looks like a bug to me. If you can find a way to make a minimal reproducible example that I could run on my machine, that would be useful.

I am working on re-writing the uploadProgress logic right now, so it would be good to see if my changes fix this or not.

I've made a minimal reproducible example here. Clone this repo and checkout the ky-upload branch, then run node ./server.js start the service.

Hope it helps.

Same here, we get an ERR_ALPN_NEGOTIATION_FAILED error when using with onUploadProgress to post form data to a Next.js API route.

Ky v1.11.0 includes a rewrite of the progress callbacks and resolves a number of small bugs and inconsistencies. I haven't investigated this particular issue yet, but the update is worth a try if you haven't already.

I tried Ky v1.13.0, but it failed again. I can reproduce in Microsoft Edge 141.0.3537.99 and Google Chrome 144.0.7501.2
