A task in Сron to update the certificate

I try to update the certificate once with the cron command @monthly echo <here my e-mail> | sudo /usr/share/jitsi-meet/scripts/install-letsencrypt-cert.sh >/dev/null 2>&1, but why does it not work.

The cron service is now operational.

$ systemctl status cron.service

By the way, after running the script manually, I saw the following.

Warning:

The JKS keystore uses a proprietary format. It is recommended to migrate to PKCS12 which is an industry standard format using "keytool -importkeystore -srckey

store /etc/jitsi/videobridge/meet.sustems.eu.jks -destkeystore /etc/jitsi/videobridge/meet.sustems.eu.jks -deststoretype pkcs12".

I just have to run this command in bash? Thank you for your answers!
