The following error message emitted from org.elasticsearch.action.support.replication.ReplicationOperation is misleading:

```
Not enough active copies to meet shard count of [1] (have 1, needed 1)
```

full context:
```
org.elasticsearch.transport.RemoteTransportException: [es-es-index-58f985f8f-pgls6][10.2.12.197:9300][indices:data/write/bulk[s][p]]
Caused by: org.elasticsearch.action.UnavailableShardsException: [.security-7][0] Not enough active copies to meet shard count of [1] (have 1, needed 1). Timeout: [1m], request: [BulkShardRequest [[.security-7][0]] containing [index {[.security][myrole], source[{"enabled":true,"roles":["myrole"],"rules":{"all":[{"field":{"realm.name":"myrealm"}},{"field":{"username":"me"}}]},"metadata":{},"doc_type":"role-mapping"}]}] and a refresh]
```

The message appears to be due to the calculation for wait_for_active_shards only counts search shards, but the message is constructed by counting all shards. In stateless this message can mean that the search shard is not available.
