Timeout in Azure DevOps for iOS when pushing to Testflight

Question

In Azure DevOps, we have a Release pipeline to push our iOS app's .ipa to Testflight, using the following extension plugin: https://github.com/microsoft/app-store-vsts-extension

Apple enforced the use of the App Store Connect API key recently.

Since implementation of the App Store Connect API key, we are now faced with a timeout error (logs as follows):

The job process fails with the following fastlane error:

2021-03-18T18:05:40.4539710Z ##[error]Error: The process '/usr/local/lib/ruby/gems/2.7.0/bin/fastlane' failed with exit code 1

1. The build is pushed to Testflight.
2. Release notes are not published.
3. I have the App manager role on the user.

What am I missing?

Answer 1

I was missing the App Manager role on the API key as suggested by Paulw11.

After regenerating a new API key with this role, it worked.

Note: App Manager role on the user account is not sufficient and it will not work if you are automating the release part (changelogs, release notes etc.)
