Issue Description

The hockey() command on the latest fastlane 2.42.0 produces the following error. Using the exact same input on 2.41.0 is actually fine. We use CircleCI with XCode 8.3, also tested using XCode 8.2 with no difference.

We also tried purging our CircleCI caches to make sure nothing weird was getting in the way.

hockey( api_token: ‘our token’, owner_id: ‘our owner’, notes: ‘changelog’, create_update: false, strategy: ‘replace’ )

It’s also interesting that the build actually gets uploaded into hockey-app when this error occurs which leads me to believe there is some kind of error during the response from hockey-app.

For now, we have rolled back to 2.41.0 to work around this problem.

Specific error is: TypeError: [!] no implicit conversion of nil into String
