Hello! i have snapshot repository which is located on NFS share, and i'm try to register repo from my local ES instance and got strange error

```auto
curl -X PUT "192.168.2.11:9200/_snapshot/delete_after_read?pretty" -H 'Content-Type: application/json' -d'
 {
   "type": "url",
   "settings": {
     "url": "file:/opt/elasticsearch-backup/elastique-backup"
   }
 }
 '

{
  "error" : {
    "root_cause" : [
      {
        "type" : "array_index_out_of_bounds_exception",
        "reason" : "Index 0 out of bounds for length 0"
      }
    ],
    "type" : "array_index_out_of_bounds_exception",
    "reason" : "Index 0 out of bounds for length 0"
  },
  "status" : 500
}

```

Can you share the output of that call when adding the parameter `error_trace=true` and share the whole output in a gist?

That said, how about using the `fs` repository instead? Alternatively you may want to try `file:///opt/...` for the `url`.

Shouldn't you be using;

```auto
curl -X PUT "host:9200/_snapshot/delete_after_read?pretty" -H 'Content-Type: application/json' -d'
{
  "type": "fs",
  "settings": {
    "location": "/opt/elasticsearch-backup/elastique-backup",
  }
}

```
