(nice if you could space the output.. :)

I was experiencing this issue in my pipeline. The culprit is

2021-12-22T13:41:25.5723370Z /usr/local/lib/ruby/gems/2.7.0/gems/fastlane-2.199.0/spaceship/lib/spaceship/connect_api/token.rb:71:in initialize': string contains null byte (ArgumentError) 2021-12-22T13:41:25.5724890Z from /usr/local/lib/ruby/gems/2.7.0/gems/fastlane-2.199.0/spaceship/lib/spaceship/connect_api/token.rb:71:in new'

Fastlane requires the .p8 key file in your service connection to be base64 encoded to use in the AppStoreRelease@1 task.

The issue is described here: https://github.com/microsoft/app-store-vsts-extension/issues/219

Try updating your service connection Key Content with a base64 encoded key. You can use the tool https://www.base64encode.org/ to complete online
