Fastlane task fail

[Parigi65]

I don't understand why this task fail when bamboo run it and it is ok if I perform it locally on my Mac

Starting task 'Build and upload to Testflight' of type 'com.atlassian.bamboo.plugins.xcode.bamboo-xcode-plugin:fastlaneTaskType'

Failing task since return code of [/var/folders/7p/fbd7gb613c55gkt9386dlx5w0000gp/T/epb2966327233818768158.sh fastlane ios beta] was -1 while expected 0
