Recently, a type of upload error has been occurring frequently, manifesting as:

1Metadata validation failed: Deprecated Transporter usage. You are required to use the -assetFile command instead of the -f command with your .ipa or .pkg files. Additionally, to continue uploading apps using the Aspera and Signiant delivery methods, you are required to use Transporter 4.2 or later. (1046)

Some developers encounter this error when:

  • Xcode upload
  • altool upload
  • old version upload scripts
  • third-party upload tools (e.g., AppUploader old channel; test shows switching to new channel works)

The error is “Metadata validation failed”. In fact, the problem is that Apple adjusted the Transporter upload interface and restricted the old upload method.

This article addresses the issues: why it occurs, how to locate the problem, and how to replace the upload method.


What does this error actually mean

Several key terms in the error:

Deprecated Transporter usage: The current upload method has been marked as an old interface by Apple.

use the -assetFile command instead of the -f command: Apple requires a new upload parameter format.

xxxxxxxxxx Transporter 4.2 or later: The old upload component can no longer work.


Which situations are prone to occur

This problem mainly occurs in:

Scenario Trigger Reason
Old version altool Using old parameters
Old iTMSTransporter Version too low
Old upload scripts Calling deprecated interfaces
Some old upload tools Bundled old Transporter

IPA is fine, but upload fails

Many people mistakenly think there is a problem with the IPA build or certificate expiration. In fact, checking reveals the IPA is fine and App Store Connect is also normal.

The issue only occurs during upload, meaning the upload protocol is outdated, not the package itself.

The real solution is to change the upload channel. Since the problem lies in the upload protocol and Transporter interface, the core fix is not modifying the IPA but replacing the upload method.


Use AppUploader new channel for upload

This problem appears in the old upload interface.

You can directly use the new channel upload method of AppUploader (Happy App Store Submission).

Steps:

  1. Open the submit upload page, go to Submit Upload
  2. Select IPA, load the already built .ipa
  3. Set Apple App-Specific Password. Note: It is not your Apple ID login password, but an App-Specific Password.
  4. Switch to the new channel: In the upload channel settings, select the new channel and do not use the old channel.
  5. Re-upload. After executing, it will use the new Transporter upload method, and the build can enter App Store Connect normally.

Why does changing the channel solve the problem

The key here is that different channels use different underlying upload components.

Old channel: uses old Transporter parameters

New channel: adapts to Apple’s new interface

Therefore, the upload method needs to be updated.
