Not changing from RUNNABLE to RUNNING - AWS Genomic Nextflow Workshop

We are working on the below Workshop: We follow the workshop as https://github.com/aws-samples/aws-genomics-nextflow-workshop

and we have used the below cloud Formation file for resource creation: • https://console.aws.amazon.com/cloudformation/home?#/stacks/new?stackName=Nextflow&templateURL=https://s3.amazonaws.com/pwyming-demo-templates/nextflow-workshop/cloud9.cfn.yaml • https://console.aws.amazon.com/cloudformation/home?#/stacks/new?stackName=Nextflow&templateURL=https://s3.amazonaws.com/pwyming-demo-templates/nextflow-workshop/nextflow/nextflow-aio.template.yaml

After creating all resources and following all processes, We tried running bash command as “nextflow run hello” in Cloud9 Studio from GitHub source code (docs/modules/module-1__running-nextflow.md). AWS Batch Jobs started as “Runnable” in AWS Batch Dashboard but it is not moving "Running" State.

Expected Result: Process the .fastq files and get a result.
