--
-- 'logFile', 'failureDetails_logFile' - The path to the log file where the step failure root cause was

--
-- 'reason', 'failureDetails_reason' - The reason for the step failure. In the case where the service cannot
-- successfully determine the root cause of the failure, it returns
-- \"Unknown Error\" as a reason.
