AWS Cloudformation along with SSM Run Command error

I am trying to run the following commands like this:-

RunCommandAssociation2:
    Type: 'AWS::SSM::Association'
    Properties:
      Name: 'AWS-RunShellScript'
      Targets:
        - Key: InstanceIds
          Values:
            - !Ref Instance2
      Parameters:
        commands:
          - availability_zone=$(curl -s http://169.254.169.254/latest/meta-data/placement/availability-zone)
          - region=${availability_zone::-1}
          - aws ssm get-parameter --name /my-stack/my-parameter --query 'Parameter.Value' --output text --region "$region" >> /home/ec2-user/ip.txt
          - seed_hosts=$(aws ssm get-parameter --name /my-stack/my-parameter --query 'Parameter.Value' --output text --region "$region")
          - priv_ip=$(curl http://169.254.169.254/latest/meta-data/local-ipv4)
          - sudo docker run -it --privileged -p 9200:9200 -p 9300:9300 -e discovery.type=multi-node -e "cluster.name=my-elasticsearch-cluster" -e ELASTIC_PASSWORD=elastic -e ES_JAVA_OPTS="-Xms1g -Xmx1g" -e node.name="node-2" -e discovery.seed_hosts=["$seed_hosts"] -e network.host="0.0.0.0" -e node.roles=[master,data,ingest] -e cluster.initial_master_nodes=[node-1,node-2,node-3] -e network.publish_host="$priv_ip" -e xpack.security.enabled=false elasticsearch:8.7.0

To see the output, I ran these commands using AWS SSM run command UI and getting this as output:-

% Total % Received % Xferd Average Speed Time Time Time Current

Dload Upload Total Spent Left Speed

the input device is not a TTY

failed to run commands: exit status 1

Can anyone please help me understand, what could be the issue? Thanks in advance!
