How to send attachment from one instance to other instance using rest api in servicenow?

[sangitakumari]

 Hi ,

I have written the code but not moving attachment from one instance to other instance.

I have used Rest api 

i have written code but not moving from one instance to other instance ,kindly provide me is it correct if not correct then provide step by step .

(function executeRule(current, previous /*null when async*/ ) {
try {

var incObj = {};
incObj.caller_id = current.caller_id.toString();
incObj.state = current.state.toString();
incObj.short_description = current.short_description.toString();
incObj.correlation_id = current.sys_id.toString();
incObj.work_notes = current.work_notes.getJournalEntry(-1);
incObj.attachment = b64attachment;
incObj.file_name = attachment.getValue('file_name');
incObj.comments = current.comments.getJournalEntry(-1);

//var tosend = JSON.stringify(body);

var attachment = new GlideRecord('sys_attachment');
attachment.addQuery('table_name', 'incident');
attachment.addQuery('table_sys_id', current.sys_id);
attachment.query();
var b64attachment = '';

if (attachment()) {
var attchmentIS = new GlideSysAttachmentInputStream(attachment.sys_id);
var bytearrayOS = new Packages.java.io.ByteArrayOutputStream();

//write byte stream*/
attachmentIS.writeTo(bytearrayOS);

/*encode attachment file*/

b64attachment = GlideBase64.encode(bytearrayOS.toByteArray());

/*ebond the ticket*/

var r = new sn_ws.RESTMessageV2('Create in dev2 instance', 'attachment');

r.setRequestBody(JSON.stringify(incObj)); // sending the data to the REST message.

var response = r.execute();
var responseBody = response.getBody();
var httpStatus = response.getStatusCode();

var crid = JSON.parse(responseBody);
current.correlation_id = crid.result.sys_id.toString();

gs.log("request body:" + responseBody);

}
} catch (ex) {
var message = ex.message;
}

})(current, previous);

@sangitakumari Please try using "Rest API Explorer" to add attachment to same instance first and then just change the instance name to target instance
