Index with ! in their name cant be selected for recovering

[Pedy]

I have an ES cluster whith indices name like web.analytics.data.api!monthly!2018-07_v0 and doing regular snapshots/backups

Now, when I want to restore all of them, all works pretty well. If I want to restore just a specific index however, es wont do it. The command I use:

curl -X POST "localhost:9200/_snapshot/s3_backups/20191218_060001/_restore?pretty&wait_for_completion=true" -H 'Content-Type: application/json' -d'
{
  "indices": "web.analytics.data.api!monthly!2018-07_v0",
  "index_settings": {
    "index.number_of_replicas": 0
  }
}
'

The result I get is:

{
  "snapshot" : {
    "snapshot" : "20191218_060001",
    "indices" : [ ],
    "shards" : {
      "total" : 0,
      "failed" : 0,
      "successful" : 0
    }
  }
}

Please note, that If I use index without ! in its name (e.g. .kibana ), it works well. Any ideas of how I can solve that? Preferably without telling developers to rename the indices. The ES in question has version 1.7.3 I am aware it is EOL, but it is what I have to work with right now.

What worked for me when i had a % in the Index name was to use the url encoded Version
For you that would be
web.analytics.data.api%21monthly%212018-07_v0
(used https://www.urlencoder.org/ to encode it)

Thanks for your response!
What I read it, i though 'That must be it!' but unfortunately, the result is the same

So.. yeah, it was my bad in the end... the developer which requested it had typo in the index name. The others I tried the restoration on was picked by me so it was right and also somebody told me that exclamation mark is problematic, so i did not double check. Thanks for help
