// Add your code here
var attachment = new GlideRecord('sys_attachment');
attachment.addQuery('table_name', 'incident');
attachment.query();
if (attachment.next()) {
var gr = new GlideRecord('u_azure_devops');
gr.addQuery('parent', current.getUniqueValue());
gr.query();
if (gr.next()) {
// Check if the attachment already exists on the destination record
var existingAttachment = new GlideRecord('sys_attachment');
existingAttachment.addQuery('table_name', 'u_azure_devops');
existingAttachment.addQuery('table_sys_id', gr.getUniqueValue());
existingAttachment.addQuery('file_name', attachment.file_name);
existingAttachment.query();
if (!existingAttachment.next()) {
GlideSysAttachment.copy('incident', current.getUniqueValue(), 'u_azure_devops', gr.getUniqueValue());
}
}
}
})(current, previous);

Hi @vardini ,

Please update your script like below and try.

var gr = new GlideRecord("sys_attachment");
gr.addQuery("table_sys_id",current.sys_id);
gr.addQuery("table_name","u_azure_devops");
gr.query();
if(gr.getRowCount()==0) {
//add your copy script here
GlideSysAttachment.copy('incident', current.parent, 'u_azure_devops', current.sys_id);
}

Please refer below link and try the same.
