Need help in calling the Calorie Mama API in React Native

[SpeedyJeremy]

Hi all, I'm currently facing an issue of accessing the Calorie Mama API which I could not solve for a few days straight. This is my final year project and it means a lot to me if anyone would be able to help me out on this matter.

Here's my code to access the API:
` const photo = await camera.current.takeSnapshot({
quality: 70
});
// For sending image to Calorie Mama API!!!
const file = await fs.readFile(photo.path, "base64");
const data = decode(file);

    try {
        const response = await fetch("https://api.caloriemama.ai/v1/foodrecognition", {
            method: "POST",
            headers: {
                "Content-Type": "image/jpeg",
                "Authorization": "OAuth " + USER_KEY
            },
            body: {
                file: data
            }
        });
        console.log(response);
    }
    catch(e) {
        console.error(e);
    }`

I keep getting the status code of "401" which is actually a "bad authorization" problem based on the Calorie Mama documentation.
Really need some help on this! Will be grateful if anyone could help.
