How to get the volumeid for the device mounted at /dev/sdf for a particular instance with aws cli?

I am trying to get the volume id of the device mounted at /dev/sdf to a particular instance.

Command: aws ec2 describe-volumes --filters Name=attachment.instance-id,Values=$instance_id_main --region us-west-2 --output json

Output:

{
    "Volumes": [
        {
            "AvailabilityZone": "us-west-2a", 
            "Attachments": [
                {

            ], 
            "Tags": [
                {
                    "Value": "NewVolume", 
                    "Key": "Name"
                }
            ], 
            "Encrypted": false,

                    "InstanceId": "i-073cfdf5832e5a7ab", 
                    "VolumeId": "vol-0189e6a20392bb709", 
                    "State": "attached", 
                    "DeleteOnTermination": true, 
                    "Device": "/dev/sda1"
                }
            ], 
            "Tags": [
                {
                    "Value": "NewTesting", 
                    "Key": "Name"
                }
            ], 
            "Encrypted": false, 
            "VolumeType": "gp2", 
            "VolumeId": "vol-0189e6a20392bb709", 
            "State": "in-use", 
            "Iops": 100, 
            "SnapshotId": "snap-0a642b1f5be55819a", 
            "CreateTime": "2017-06-15T12:57:46.027Z", 
            "Size": 8
        }
    ]
}

I have tried with --query option of describe volume given in the example then I got below output.

Command:

aws ec2  describe-volumes --filters Name=attachment.instance-id,Values=$instance_id_main --query 'Volumes[*].{ID:VolumeId,Tag:Tags}' --region us-west-2 --output json

[
    {
        "Tag": [
            {
                "Value": "NewVolume", 
                "Key": "Name"
            }
        ], 
        "ID": "vol-096ca253d37b3e42b"
    }, 
    {
        "Tag": [
            {
                "Value": "NewTesting", 
                "Key": "Name"
            }
        ], 
        "ID": "vol-0189e6a20392bb709"
    }
]

Then I tried to get the Attachments and I got below error.

Command:

aws ec2  describe-volumes --filters Name=attachment.instance-id,Values=$instance_id_main --query 'Volumes[*].{Attachments:Device[*]}' --region us-west-2 --output text

Output:

[
    {
        "Attachments": null
    }, 
    {
        "Attachments": null
    }
]

Any idea would be appreciated.

Solution

die() { status=$1; shift; echo "FATAL: $*"; exit $status; }
EC2_INSTANCE_ID="`wget -q -O - http://169.254.169.254/latest/meta-data/instance-id || die \"wget instance-id has failed: $?\"`"
EC2_AWSAVZONE=$(curl -s http://169.254.169.254/latest/meta-data/placement/availability-zone)
EC2_REGION=${EC2_AWSAVZONE::-1}

DATA_VOLUME_ID="`aws ec2 describe-volumes  --filters Name=attachment.device,Values=/dev/sdf Name=attachment.instance-id,Values=$EC2_INSTANCE_ID --query 'Volumes[*].{ID:VolumeId}' --region $EC2_REGION --output text`"

echo $DATA_VOLUME_ID

Output:

vol-096ca253d37b3e42b
