I am using aspose.pdf 19.12. While creating a pdf with multiple fileattachmentannotations, it’s working up to 2 or 3 attachments but failing with more than that.
Following is the exception I am getting.
System.AggregateException: One or more errors occurred. (Object reference not set to an instance of an object.) —> System.NullReferenceException: Object reference not set to an instance of an object.
