When trying to read all snaphots from the repository in s3 we are getting the error:

```auto
[user@adapt103:~]$ curl 'http://localhost:9200/_cat/snapshots/adapt-prod_202111?pretty'
{
  "error" : {
    "root_cause" : [
      {
        "type" : "repository_exception",
        "reason" : "[adapt-prod_202111] could not read repository data from index blob"
      }
    ],
    "type" : "repository_exception",
    "reason" : "[adapt-prod_202111] could not read repository data from index blob",
    "caused_by" : {
      "type" : "i_o_exception",
      "reason" : "Exception when listing blobs by prefix [index-]",
      "caused_by" : {
        "type" : "sdk_client_exception",
        "reason" : "sdk_client_exception: Unable to execute HTTP request: adapt.s3.amazonaws.com",
        "caused_by" : {
          "type" : "i_o_exception",
          "reason" : "adapt.s3.amazonaws.com"
        }
      }
    }
  },
  "status" : 500
}

```

When I list repositories it works:

```auto
[user@adapt103:~]$ curl 'http://localhost:9200/_cat/repositories?pretty'
adapt-prod_202111 s3
adapt-prod_202110 s3

```
