Hi,  
I'm using the new Java elasticsearch client to PUT a logstash pipeline (client version 8.4.1, server 8.4.1)

```auto
client.logstash().putPipeline(b -> b
                        .id(id)
                        .pipeline(p -> p
                                .description(id)
                                .lastModified(DateTime.ofEpochMilli(System.currentTimeMillis()))
                                .pipeline("input {}\n filter { grok {} }\n output {}")
                                .username("elastic")
                                .pipelineMetadata(m -> m
                                        .type("logstash_pipeline")
                                        .version("1")
                                )
                                .pipelineSettings(s -> s
                                        .pipelineBatchDelay(50)
                                        .pipelineBatchSize(125)
                                        .pipelineWorkers(1)
                                        .queueCheckpointWrites(1024)
                                        .queueMaxBytesNumber(1)
                                        .queueMaxBytesUnits("gb")
                                        .queueType("memory")
                                )
                        )
                )

```

Bu I get an error on the `last_modified` field:

```

Am I doing something wrong or is it a bug?

Check the [documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/logstash-api-put-pipeline.html#logstash-api-put-pipeline-request-body).

> `last_modified`  
> (Required, string) Date the pipeline was last updated. Must be in the `yyyy-MM-dd'T'HH:mm:ss.SSSZZ` [`strict_date_time`](https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-date-format.html) format.

The value for the `last_modified` needs to be in this format: `yyyy-MM-dd'T'HH:mm:ss.SSSZZ`

But from your log you are sending it as a number, with the date in epoch time.

> "{"description":"org\_dataset"," **last\_modified**": **1662024280651**

As you can see, I'm sending it as a DateTime object which is what is required by the `lastModified(DateTime value)` method of the java client.

This is not what your log shows, the Debug line of your request shows that the `last_modified` is a number.

> DEBUG [2022-09-01 09:24:40,766] org.apache.http.wire: http-outgoing-1 \>\> "{"description":"org\_dataset","last\_modified": **1662024280651**

Maybe this is a bug then? You should open an issue to see if someone can help you better, but have you tried to format the date to see if it works?
