linux cron debian bash

This might be a silly question, but I'm working through a tutorial and I'm writing unit tests and I'm working on a project and hit a roadblock... I'm working with an scenario where a cron job on my Debian 11 server is failing to execute a shell script. The script is located at `/usr/local/bin/myscript.sh` and is supposed to run every day at midnight. However, I keep getting a 'Permission denied' behavior in the cron log. Here’s the relevant part of my crontab: ```bash 0 0 * * * /usr/local/bin/myscript.sh ``` I've ensured that the script has the executable permission set using: ```bash chmod +x /usr/local/bin/myscript.sh ``` When I try to run the script manually from the terminal, it works perfectly: ```bash /usr/local/bin/myscript.sh ``` The script itself is quite simple, it just outputs a message to a log file: ```bash #!/bin/bash echo "Script executed at $(date)" >> /var/log/myscript.log ``` I checked the ownership of the script and it is owned by `root:root`. The cron service is running, and the cron logs show the following message when it attempts to execute the job: ``` /bin/sh: 1: /usr/local/bin/myscript.sh: Permission denied ``` I've also confirmed that `/var/log/myscript.log` is writable by the script, and I can write to it manually. Additionally, I tried running the cron job as root by editing the root's crontab, but the scenario continues. What else could be causing this 'Permission denied' behavior? My development environment is macOS. What's the best practice here? I'm coming from a different tech stack and learning Bash. What are your experiences with this? I'm working with Bash in a Docker container on Windows 11. Thanks for your help in advance! I'm using Bash 3.9 in this project. I'd really appreciate any guidance on this.
