NoMethodError: undefined method `unpack1' for nil:NilClass

[Baaboud]

we get this error when there is an empty file is uploaded in our application because the data part is blank
for example "data":"data:text/plain;base64,"

sometimes we are expecting empty files to be uploaded

I think we should consider allowing empty data part to be blank or adding validation to allow or prevent empty files

lib/active_storage_support/base64_attach.rb:22
decoded_data  = Base64.decode64(data || '')
