Customising print format error

Hi everyone,
I’m new to erpnext, currently on self hosted ubuntu 18.04 vm on proxmox. When saving a custom print format (without even changing any fields in the the custom format) and try invoking it in stock entry print format , I received the following error message “AttributeError: ‘PrintFormat’ object has no attribute ‘absolute_value’”

frappe log:

I did it on a newly installed instance. So no data entry has been recorded.

Do you know how to take a backup and restore safetly ,could there be any issue happen in between in migrate ?
