Briefcase Internal server error

Hi

I want to backup/restore at two stages in kobotoolbox

1- Submission data backup/estore

I have used briefcase for this. Pull is successful. I have deleted some submissions by kobo GUI. I have pushed wtih briefcase. It has given error. but when I go to kobo GUI, I have seen that deleted records are restored. WHy it has given Internal server error? Am I doing something wrong?

java -jar ODK-Briefcase-v1.14.0.jar --push_aggregate --form_id aGce2syimGAyqn4hZcw5QL --storage_directory briefcase --aggregate_url https://kc.humanitarianresponse.info/USER --odk_username USER --odk_password PASSWORD

2- submission + form backup restore

I have deleted form/project from kobo
I have pushed form with birefcase. But it did not work. I could not see the form in kobo GUI? What is the problem? It gives internal server error

java -jar ODK-Briefcase-v1.14.0.jar --push_aggregate --form_id aGce2syimGAyqn4hZcw5QL --storage_directory briefcase --aggregate_url https://kc.humanitarianresponse.info/USER --odk_username USER --odk_password PASSWORD
