Why is postgresql backup script not running in Cron?

Question

Task Schedulers

Good afternoon, I have a database backup script that runs fine from the CLI, but does not run through CRON, the logs do not show anything

Script

#!/bin/sh

# Backing up
docker exec -t pgstaff_postgres_1 pg_dumpall -c -U estaffuser | zstd  > /docker/backup/estaffdb_$(date +"%Y-%m-%>

# Rotating the logs, delete older than 31 days
find /docker/backup/estaffdb_* -mtime +31 -exec rm {} \;

crontab -e

0 3 * * * /root/scripts/estaff_backup.sh

CRON log

Answer 1

The problem was solved by restarting the cron service: systemctl restart cron.service
It is strange of course why this is so

Answer 2

why did you show the log only up to 2 hours? ))
okay. is the script executable? Some kind of SELinux or AppArmor in the system is not weird? Have you tried changing sh to bash?
