Issue Description

Running fastlane pilot add doesn’t add the tester, but errors with:

[!] Some operations failed: [testername@example.com]: User [appleid@example.com] (Team ID [123456]) doesn't have enough permission for the following action: parse_response

This is with an App Developer role, which has permission to add testers when done through iTC. Likely related, trying to upload a csv of testers fails with unable to add tester for each row in the csv.

Complete output when running fastlane, including the stack trace and command used

You can use: --capture_output as the last commandline argument to get that collected for you
