AWS ECS docker Invalid 'volumesFrom' setting. Unknown container - amazon-web-services

Question

I am trying to run service with following definition on AWS ECS cluster. But I am getting an error. Invalid 'volumesFrom' setting. Unknown container: 'docker-data'. I have separately launched docker-data service but my other service is still unable to find my data container. Below are task definitions.
{
"containerDefinitions": [{
"name": "docker-data",
"image": "jaigouk/data-only-container",
"memory": 128
}],
"family": "docker-data"
}
{
"containerDefinitions": [{
"image": "my/work-image",
"name": "image2",
"memory": 512,
"portMappings": [{
"hostPort": 8040,
"containerPort": 8040,
"protocol": "tcp"
}],
"volumesFrom": [{
"sourceContainer": "docker-data"
}]
}],
"family": "console"
}

Looks like you're defining 2 containers in two task definitions. In this case, docker-data is not known.
Here is one of my working example
{
"taskDefinitionArn":"arn:aws:ecs:ap-southeast-1:xxxx:task-definition/vc-p-tim:15",
"networkMode":"bridge",
"status":"ACTIVE",
"revision":15,
"taskRoleArn":null,
"containerDefinitions":[
{
"volumesFrom":[
],
"memory":2048,
"extraHosts":null,
"dnsServers":null,
"disableNetworking":null,
"dnsSearchDomains":null,
"hostname":null,
"essential":true,
"entryPoint":null,
"mountPoints":[
{
"containerPath":"/apps",
"sourceVolume":"tinymce-data",
"readOnly":null
}
],
"name":"tim-srv",
"ulimits":null,
"dockerSecurityOptions":null,
"environment":[

"links":null,
"workingDirectory":null,
"readonlyRootFilesystem":null,
