Cannot find write index

Elastic Stack Elasticsearch

Welcome!

Please read this about how to format.

You need to use the update settings API and not the create index if your index already exists I guess.

PUT /cedar-00001/_settings
{
  "aliases" : {
    "cedar_log" : {
      "is_write_index": true
    }
  }
}

But I don't know if this is what you really want to do...
