Oddly I am getting a very similar error on attempting to upload a Backup file of around 50MB. This is on a totally clean, new Digital Ocean-based image that I just finished setting up, running 2.8.0.beta11 (232f840b60). I increased all file size limits within the admin settings. Error log shows:
TypeError: e._perFileData is not a function

Then a few minutes later, after following these instructions to change max attachment size (because I don’t know what else it could be), I get:

Tried in 3 separate browsers. I’ve redacted the specific subdomain, but I wouldn’t think that should matter.
I’m only posting here because it’s literally the only other mention I can find of these errors, and it’s recent so I thought it might be related. Apologies if it’s OT.
