Restoring index from S3 Snapshot

Elastic Stack Elasticsearch
1

I am trying to restore a single index from S3 snapshot and I am getting the following error

curl -XPOST "http://localhost:9200/_snapshot/s3_rep/snapshot_events_2015_07_2015_11_01/_restore" -d '{
"indices": "events-2015.07.01",
"ignore_unavailable": "true",
"include_global_state": false
}'

{"error":"ElasticsearchIllegalArgumentException[failed to parse repository source [{\n "indices": "events-2015.07.01",\n "ignore_unavailable": "true",\n "include_global_state": false\n}]]; nested: ElasticsearchIllegalArgument

The path does exist, I am able to list the index successfully using the

curl -s -XGET "localhost:9200/_snapshot/s3_rep/snapshot_events_2015_07_2015_11_01/_status?pretty" | grep events-2015.07.01
"events-2015.07.01" : {

Is there more to the error?
Is there anything in the ES logs?

There is no error in the ES logs, I have ran this command in the past when my ES was 1.4.5
Nothing else has changed except my ES is now 1.7.1
Is there a change on the syntax to restore and index from S3 snapshot?

curl -XPOST "http://localhost:9200/_snapshot/s3_repository/snapshot_events_2015_07_2015_11_01/_restore" -d '{
"indices": "events-2015.07.01",
"ignore_unavailable": "true",
"include_global_state": false
}'

{"error":"ElasticsearchIllegalArgumentException[failed to parse repository source [{\n "indices": "events-2015.07.01",\n "ignore_unavailable": "true",\n "include_global_state": false\n}]]; nested: ElasticsearchIllegalArgumentException[Unknown parameter ignore_unavailable]; ","status":400} tmp]$
