    }
    var data = CloudCode.callTask('getData', params)
    var attachment = Attachment.create({
        filename: "example.pdf",
        mediaType: "application/pdf",
        base64: data
    });
    journey.files.viewFile(attachment);
}

CloudCode

export async function run(params) {
    // Your code here
    var url = params && params.url ? params.url : "https://www.w3.org/WAI/ER/tests/xhtml/testfiles/resources/pdf/dummy.pdf";
    var response = await fetch(url, {method: "GET", mode: 'no-cors'});
    var buffer = await response.buffer();

    // return data
    return buffer.toString('base64');      
}
