send attachment from an instance to another

[MohamedAliE]

in my BR : i wrote this : 

function sendAttachment(targetSysId) {

    var grAttach = new GlideRecord('sys_attachment');

    grAttach.addQuery('table_sys_id', current.sys_id);

    grAttach.query();

    while (grAttach.next()) {

        var fileName = grAttach.file_name.toString();

        var contentType = grAttach.content_type.toString() || 'application/octet-stream';

        var binData = new GlideSysAttachment().getBytes(grAttach);

        try {

            var rm = new sn_ws.RESTMessageV2('Upload Attachment to LVER DEV', 'POST');

            // Endpoint avec sys_id cible et nom de fichier

            var endpoint = rm.getEndpoint()

                .replace('${table_name}', 'incident')

                .replace('${table_sys_id}', targetSysId)

                .replace('${file_name}', encodeURIComponent(fileName));

            rm.setEndpoint(endpoint);

            rm.setHttpTimeout(60000);

            // Le binaire directement dans le body

            rm.setRequestHeader("Content-Type", contentType);

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

            rm.setRequestBody(binData);

            var resp = rm.execute();

            var body = resp.getBody();

            var status = resp.getStatusCode();

            gs.log("Attachment sent: " + fileName + " | MIME type: " + contentType + " | Status: " + status + " | Response: " + body);

        } catch (e) {

            gs.log("Error sending attachment " + fileName + ": " + e.message);

        }

    }

}

but in my instance cible the file are truncated 😞

if yes then check these links

i found a solution it seems work : 

function sendAttachment(targetSysId) {

    var sa = new GlideSysAttachment();

    // 1️⃣ Supprimer les anciens attachments sur l'incident cible (to update docs)

    var grTargetAttach = new GlideRecord('sys_attachment');

    grTargetAttach.addQuery('table_sys_id', targetSysId);

    grTargetAttach.query();

    while (grTargetAttach.next()) {

        sa.deleteAttachment(grTargetAttach.sys_id);

        gs.log("Deleted old attachment on target: " + grTargetAttach.file_name);

    }

    // 2️⃣ Parcours des attachments source et envoi

    var grSourceAttach = new GlideRecord('sys_attachment');

    grSourceAttach.addQuery('table_sys_id', current.sys_id);

    grSourceAttach.query();

    while (grSourceAttach.next()) {

        var fileName = grSourceAttach.file_name.toString();

        var contentType = grSourceAttach.content_type.toString() || "application/octet-stream";

        var rm = new sn_ws.RESTMessageV2('Upload Attachment to LVER DEV', 'POST');

        rm.setEndpoint(rm.getEndpoint()

            .replace('${table_name}', 'incident')

            .replace('${table_sys_id}', targetSysId)

            .replace('${file_name}', encodeURIComponent(fileName))

        );

        rm.setRequestHeader("Content-Type", contentType);

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

        rm.setRequestBodyFromAttachment(grSourceAttach.sys_id);

        var resp = rm.execute();

        gs.log("Attachment sent: " + fileName + " | Status: " + resp.getStatusCode() + " | Response: " + resp.getBody());

    }

}

thank you
