Exception occurred when creating MZContentProviderUpload for provider. (1004)

Question

I tried to upload the app build using Xcode but I got this error "no accounts with itunes connect access" I then tried to upload the IPA using application loader and I got this error "Exception occurred when creating MZContentProviderUpload for provider. (1004)"

Answer 1

It seems like a temporary issue with apple. Trying few times to send worked and the upload was successful.

Answer 2

For me just log out on Web iTunesConect / AppsoreConnect portal.

Quit Xcode (if Possible restart) and then upload the build.

If you close all the other app and upload build in sylo makes a job easy.

Also using the "Application Loader" is a Good Solution!

Answer 3

I was facing same issue. In my case I tried to login another Apple Developer account via Safari. I solved this by doing:

Logout the account from Xcode and login again. It works successfully for me. No need to generate build again.
