        if ((frm.selected_workflow_action === 'Send to agency')) 
       
        {
            
          frm.set_value("date_of_receipt_from_agency", frappe.datetime.now_datetime());
            frm.refresh();

Hello @Osk ,

Try will server script.

if doc.workflow_state == "YOUR NEXT WORKFLOW STATE" and not doc.field_name:
   frappe.throw("field_name is mandatory")

Example

if doc.workflow_state == "Approved" and not doc.approver:
   frappe.throw("approver is mandatory")

there is an error in syntax
