ServiceNow to AWS s3 Attachment Post Script

[BatuhanP]

Hello. I want to send attachments from ServiceNow incident_task to an AWS S3 server provided by a third-party software. I managed to upload something and received a 201 status code. However, when downloading the file from S3, the file structure is corrupted. No matter what I try, the file structure on the other side always seems corrupted. What could be causing this issue? Please help, I've been struggling with this for two weeks.

Code :

Please help me guys

 var attachmentGR = new GlideRecord('sys_attachment');
    attachmentGR.addQuery('table_sys_id', current.sys_id);
    attachmentGR.query();
    if (attachmentGR.next()) {
        var attachmentContent = new GlideSysAttachment();
        var fileContent = attachmentContent.getBytes(attachmentGR);
        var fileContentBase64 = GlideStringUtil.base64Encode(fileContent); // fileContent'i base64'e dönüştür
		var fileContentBase64Decode = GlideStringUtil.base64Decode(fileContent);
        var contentTypee = attachmentGR.content_type.toString(); // Dosya tipini alın
        var filename = attachmentGR.file_name.toString();
        var keyAndName = fileKey.replace('${filename}', filename); // keyAndName'i oluşturun
		}
