I have this cron schedule.
0 8 * * * cd /home/deploy/frappe-bench && /usr/local/bin/bench execute residences.task.generate_jv_billing > /home/deploy/frappe-bench/logs/generate_jv_billing.log 2>&1
but error occurred in the log file
sage: bench [OPTIONS] COMMAND [ARGS]...
Error: No such command "execute".
Why bench cannot recognized the execute command?
