I am getting error 400 while sending attachment using the below code. Request to kindly help.

The business rule code :

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

    var targetInstanceURL = "https://dev****.service-now.com/";

    var targetUserID = "******";

    var targetUserPassword = "******";

    var text = "";

    var attachmentMsg = "";

    try {

        var r = new sn_ws.RESTMessageV2("KB_Bonding", "Create record");

        r.setStringParameter('sys_id', current.sys_id);

        r.setStringParameter('kb_knowledge_base', current.kb_knowledge_base.toString());

        r.setStringParameter('short_description', current.short_description);

        var response = r.execute();

        var responseBody = response.getBody();

        var httpStatus = response.getStatusCode();

        if (httpStatus.toString() === '201') {

            text = "Knowledge created successfully.";

            var parsed = JSON.parse(responseBody);

            var targetRec = parsed.result.sys_id;

            //gs.log(targetRec, 'Target KB sys_id');

            var attachmentCount = sendAttachments(current.getTableName(), current.sys_id.toString(), targetRec);

            gs.log(attachmentCount+"-"+current.getTableName()+"-"+current.sys_id.toString()+"-"+targetRec,"<attachmentCount>");

            if (attachmentCount > 0) {

                attachmentMsg = "Attachments successfully sent: " + attachmentCount;

            } else {

                attachmentMsg = "Record has no attachments.";

            }

        } else {

            text = "KB could not be created. Status code: " + httpStatus;

        }

    } catch (ex) {

        text = "Exception occurred: " + ex.message;

    }

    gs.addInfoMessage(text + " " + attachmentMsg);

    // Function to copy attachments

    function sendAttachments(sourceTable, sourceID, targetID) {

        var count = 0;

        var attachmentRec = new GlideRecord("sys_attachment");

        attachmentRec.addQuery('table_sys_id', "c7f0f1d2934aa210db9d7af08bba1050");

        attachmentRec.addQuery('table_name', "kb_knowledge");

        attachmentRec.query();

        //gs.log("ok","<ok_2>");

        while (attachmentRec.next()) {

            gs.log(sourceTable+","+targetID+","+attachmentRec.file_name,"<ok_3>");

            var amsg = new sn_ws.RESTMessageV2();

            amsg.setHttpMethod("post");

            amsg.setBasicAuth(targetUserID, targetUserPassword);

            amsg.setEndpoint(targetInstanceURL + "api/now/attachment/file");

            gs.log(targetInstanceURL + "api/now/attachment/file","<attachment_api>");

            amsg.setQueryParameter("table_name","kb_knowledge");

            amsg.setQueryParameter("table_sys_id","c7f0f1d2934aa210db9d7af08bba1050");

            amsg.setQueryParameter("file_name",attachmentRec.file_name);

            gs.log(attachmentRec.file_name,"<attachmentRec.file_name>");

            amsg.setRequestHeader("Accept", "application/json");

            amsg.setQueryParameter("Content-Type","multipart/form-data");

            amsg.setRequestBodyFromAttachment(attachmentRec.sys_id);

            gs.log(attachmentRec.sys_id,"attachmentRec.sys_id");

            var response = amsg.execute();

            var respStatus = response.getStatusCode();

            gs.log(respStatus,"<respStatus>"); //here I get error 400

            if (respStatus === 201) {

                count++;

            } else {

                gs.log("Failed to send attachment: " + attachmentRec.file_name + ". Status: " + respStatus);

            }

        }

        return count;

    }

})(current, previous);

The article gets created but the attachment does not go.

Hello, in sendAttachments function
this is not query parameter: amsg.setQueryParameter("Content-Type","multipart/form-data");
it should be header amsg.setRequestHeader("Content-Type", "multipart/form-data");
