Hi all,

I have a logstash output http plugin:

```auto
output {

    if [@metadata][index_to_delete] == "first_index" or [@metadata][index_to_delete] == "second_index" {
        http {
         id => "http_index_delete"
         url => "https://HOST:9200/%{[@metadata][index_to_delete]}"
         http_method => "delete"
         cacert => 'mycert.cer'
         user => "user_with_delete_index_right"
         password => "mypass"
        }
    }
}

```

An I get this error:

```auto
[2023-07-11T16:15:03,083][ERROR][logstash.outputs.http][main][http_index_delete] [HTTP Output Failure] Encountered non-2xx HTTP code 400 {:response_code=>400, :url=>"https://HOST:9200/second_index", :event=>#<LogStash::Event:0x453a6b91>}

```

It is a bad request to elasticsearch.  
How can I solve it? Is it because of credentials? Thank you

Edit: Logstash version 7.17

After days of checking for a solution, I found out that it is a known bug (open issue) in http plugin in logstash output:  
[Link to Github repo http output plugin](https://github.com/logstash-plugins/logstash-output-http/issues/137)

I found a workaround. I used http plugin in the filter section:

```auto
filter {
  if [@metadata][index_to_delete] == "first_index" or [@metadata][index_to_delete] == "second_index" {
          http {
           id => "http_index_delete"
           url => "https://HOST:9200/%{[@metadata][index_to_delete]}"
           verb => "DELETE"
           cacert => 'mycert.cer'
           user => "user_with_delete_index_right"
           password => "mypass"
          }
      }
}

```

It deleted my index in elasticsearch but tried again afterwards. I need to create an if condition to do it once.  
The only difference between filter http plugin and output http plugin is:

```auto
verb => "DELETE"

```

instead of

```auto
http_method => "delete"

```
