Amazon-Web-Services – AWS CLI cannot use cron

#!/bin/bash
PATH=/usr/local/ sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games
SHELL=/bin/bash
 
# Create EBS Data snapshot
/usr/local/bin/aws ec2 create-snapshot --volume-id "vol-XXXXX" --description "test"

Unable to locate credentials . You can configure credentials by running "aws configure".

SHELL=/bin/bash
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin: /bin

I have this script:

#!/bin/bash
PATH=/ usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games
SHELL=/bin/bash 

# Create EBS Data snapshot
/usr/local/bin/aws ec2 create-snapshot --volume-id "vol-XXXXX" --description "test"

< p>If I run it from the shell, it works well, but it has no effect on Cron. Why? I am using IAM roles, is this important?

Running aws configure as root user did not help me, because I have configured the credentials, and the script runs directly from the command line for the root user very happily, but Still can’t run through cron.
The error message I received is;

Unable to locate credentials. You can configure credentials by running "aws configure". 

What helped me was to add the following lines at the top of my crontab file to provide a proper environment for all scripts running through cron.

SHELL =/bin/bash
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

I hope someone can help !
