Your sudo is configured to only run when there is a tty
present, whcih is not the case for cron jobs.  Usually this
is due to a line like the following in sudoers:

    Defaults	requiretty

Removing this (or just disabling it for the user who must run the
cron job) should eliminate the error.  Note that you will also need
to disable authentication either via the NOPASSWD tag or the
"authenticate" Defaults option.
