Notarize the dmg file and you will get ITMS-90728.

Hello.
I tried to get multiple installation folders notarized after combining them into a dmg, but as soon as the upload was complete, it returned an ITMS-90728 error. I have tried changing the format of the folder and omitting the parts where languages other than English are used, but it does not fix the problem.
How can I fix it so that it will accept notarization without problems?
A quick ’net search reveals that ITMS-90728 means “invalid file contents”. The most common cause of this is folks trying to notarise a disk image in an unsupported format. See Signing a Mac Product For Distribution for my advice on how to create a disk image in a supported format.
