_recovery returned an empty response even if I have correct indices

[gyorgybakocs]

Hello.

We have around 500GB catalog every day.
We create daily-snapshots.
In my new task, I had to restore the latest snapshot on Monday and on Thursday.

My bash script works with this logic:

1. I search in the latest snapshot for the stored index (I used curl, and from the response, I get the index name)
2. I check our DB for this index, If it exists, just put a new alias with the actual date, If we do not have it in our DB, I restore it.

We have seven countries, so we have seven different daily-snapshot (based on the country) and in every snapshot only one index.
So... My problem. I restored the first six countries but the last one was unsuccessful.
No error message, just this:

2019-03-21 07:06:12,646 INFO      Trying Action ID: 1, "restore": Restore the latest product index
2019-03-21 07:06:12,957 INFO      Restoring indices "['product_ph_20190319']" from snapshot: snapshot_product_ph_20190321_0110
2019-03-21 07:06:13,121 INFO      _recovery returned an empty response. Trying again.

And tried, tried, tried... Like a never-ending story

in sense, I can see the correct index:

     {
         "snapshot": "snapshot_product_ph_20190321_0110",
         "uuid": "gLnd0c3ASreBRW526WeLaQ",
         "version_id": 5060699,
         "version": "5.6.6",
         "indices": [
            "product_ph_20190319"
         ],
		 ...

• I changed the config file and sent the index name (I got it from the snapshot!!!) as a variable, but the result was the same.
  (I found this with a similar problem: Curator throwing error while restoring (Failed to complete action- ) )
• with --dry-run everything works perfectly.

update:

• When I checked my free space on my instance, I realised there is not enough space to restore the index.
