 const upload = async () => { const reader = new window.FileReader(); reader.readAsArrayBuffer(inputfile); reader.onload = async () => { const result = await ipfs.add(reader.result); contract.uploadFile(result.path, result.size, type, name, "Upload by Ankit") }; }; <button onClick={upload} className="upload-btn"> Upload </button>

Cuando hice clic en el botón Upoad, se llamó a la función de carga y tengo detalles del archivo que estoy cargando en ipfs y envío los detalles a blockchain por contract.upload (.... detalles) pero recibo un error
