[SOLVED] AWS CloudWatch Rule returns FailedInvocation with AWS batch as Target

AWS CloudWatch Rule returns FailedInvocation with AWS batch as Target

Hi I've scheduled a Cloudwatch rule in order to run every Wednesday at 14.15 GTM by having as target an AWS Batch, which always returns FailedInvocation. I'm seeing the FailedInvocation event from associated metrics

However there are no logs regarding the error, I cannot understand the problem.

I've followed this tutorial: https://docs.aws.amazon.com/batch/latest/userguide/batch-cwe-target.html I'm stucked here from hours any suggestion?
