I'm trying to scan web file using clamscan but it can't scan web file. How can I fix that?

scanFile(await fetch(ImageLink))

this is not working. scanFile() is:

function scanFile(filePath) {
    return ClamScan.then(async clamscan => {
        const { is_infected, file, viruses } = await clamscan.isInfected(filePath);

        if (is_infected) {
            return viruses;
        } else {
            return false;
        }
    }).catch(err => {
        console.log(err);
    });
}

it returns NodeClamError: Invalid or empty file name provided.
