Error when restoring snapshot

I created a snaphot, the resulting files are:

  • index
  • indices (directory)
  • meta-snapshot_4-15-2015.dat
  • snap-snapshot_4-15-2016.dat

I can see all of my indices in the indices folder.

When I try to restore using

POST _snapshot/elk_backup/snapshot_4-15-2016/_restore

I get:

   "statusCode": 400,
   "error": "Bad Request",
   "message": "Missing kbn-version header"

Also, in kibana, I get "there is no default index".

I am doing this to move from kibana 4.2.1 to 4.5.0 and elasticsearch 2.0.0 to 2.3.1
