Hi, I have this function that is supposed to upload a file stream to another page:

async function getData() {
    const vocadata = await fetch('http://localhost:3000/upload/',
        {
            method: "POST",
            headers: {
                "Content-Type": "multipart/form-data",
            },
            body: data,
        });
    console.log(vocadata);
};

The problem is though, no matter what URL I enter in the first argument, it always posts the request to /. How can I fix this?
