According to [this](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-reindex.html#reindex-from-remote) piece of documentation, I need to configure `reindex.remote.whitelist` to allow reindexing from a remote elastic cluster.  
It states that the value should be a string with comma separated list of allowed hosts. Here is the example that is provided:

```auto
reindex.remote.whitelist: "otherhost:9200, another:9200, 127.0.10.*:9200, localhost:*"

```

This however results in an error message when trying to save the configuration in elastic cloud:

I found that providing an array of hosts works:

```auto
reindex.remote.whitelist:
  - "localhost:*"
  - "some.other.cluster.local:9243"

```

Is this an issue with documentation or am I missing something? Is this forum the right place to report this?
