crontab automation problem in amazon linux

Question

I'm trying to automate my some task in Amazon linux

All of my file location is /home/ec2-user/ (CRON, bash.sh)

Here is my command (I just executed this command in /home/ec2-user/)

sudo yum install -y python3 && sudo yum install -y cronie && chmod 777 bash.sh && crontab CRON && sudo service crond restart

my cron file name: CRON

and here is my code

* * * * * /bin/bash /home/ec2-user/bash.sh

my bash file name: bash.sh

and here is my code

#! /bin/bash

python3 - << 'EOF'

print("test")

EOF

but after one minutes later, I got one mail with contains error message

: No such file or directoryash.sh

I think my CRON file fail to find /home/ec2-user/bash.sh

How can I solve this problem?
