Currently when there is an error with latest version v0.22.1, the error message is not displayed.
Log fatal exits and does not print the error.

Test:
Remove createBucket permission from the role.

Expectaion:
Error is printed to screen with the error

Currently:
There is an empty screen, no log, just an exit code of 1

With this change the current error is printed before the exit.
