Getting "Content length 0 too small" when trying to upload to vimeo using tus

Question

I am trying to upload a video file to vimeo using their resumable upload protocol, but end up getting

Failed because: Error: tus: unexpected response while creating upload, originated from request (method: POST, url: https://1515143405.cloud.vimeo.com/upload?ticket_id=42606237…62378%26signature%3D19062b29129850403638ca88040debe1e21cc646, response code: 400, response text: Content length 0 too small

this error whenever I initiate the upload.

const vimeoFileUpload = async(e) => {
const fileContent = e.target.files[0];
const fileSize = fileContent.size;
const reader = new FileReader();
reader.onload = r => {console.log(r.target.result)};
let uploadLink;

await fetch(`${backendUri}/fetchUploadLink`, {
    method: 'POST',
    body: JSON.stringify({fileSize}),
    headers: {"Content-Type": "application/json"}
}).then((res) => res.json())
   .then((result) => {
       uploadLink=result.uploadLink
   });

let uploader = new tus.Upload(fileContent, {
    uploadUrl: uploadLink,
    endpoint:uploadLink,
    retryDelays: [0, 1000, 3000, 5000],
    metadata: {
        filename: "sample",
        filetype: fileContent.type
    },
    uploadSize: fileSize,
    onError: function(error) {
        console.log("Failed because: " + error);
    },
    onProgress: function(bytesUploaded, bytesTotal) {
        let percentage = (bytesUploaded / bytesTotal * 100).toFixed(2);
        console.log(bytesUploaded, bytesTotal, percentage + "%");
    },
    onSuccess: function() {
        console.log(
            "Download %s from %s",
            uploader.file.name,
            uploader.url
        );
    }
});
uploader.start();
}

This is the code for the upload function. I also tried setting Content-Length as a custom header in the tus config but it claimed it was a forbidden header and didn't let me modify it

Any thoughts or advice on the matter will be much appreciated.

The initial request to create the video is most likely malformed or invalid. For tus upload, the Vimeo API will return an upload_link on the files.tus.vimeo.com domain (or similar). Make sure the initial POST /me/videos request specifies upload.approach=tus.

Before attempting the actual file upload, you'll want to verify that the API returns upload.approach=tus.

The Vimeo API's tus docs are found here: https://developer.vimeo.com/api/upload/videos#resumable-approach
