ElasticSearch php客户端中的mapper_parsing_exception

Question

错误

[body] => {"error":{"root_cause":[{"type":"mapper_parsing_exception","reason":"failed to     parse"}],"type":"mapper_parsing_exception","reason":"failed to 
parse","caused_by":{"type":"not_x_content_exception","reason":"Compressor detection can 
only be called on some xcontent bytes or compressed xcontent ytes"}},"status":400}

将文档添加到索引时出现错误。

这就是我通过邮递员创建索引的方式。

$ result变量中的

    (
        [last_consult_by] => xxxxxx
        [mpi] => xxxxxxxx
        [bill_id] => 176073
        [bill_date] => 2018-07-12 12:00:00
        [site] => xxx
        [effective_edd] => 2018-07-28 12:00:00
        [is_converted] => 0
        [admitting_physician] => xxxxxxxxx
        [days] => 16
        [trim] => Array
            (
                [trim3] => 1
            )

    )


    $params = [
        'index' => 'patient_trimester',
        'type'  => 'patient_trimester',
        'body'  =>  $result
    ];

    $res = $client->index($params);
    print_r($res); exit;

我不明白为什么发生mapper_parsing_exception。 这是因为我映射了数据类型吗？给有效_edd，bill_date的数据类型指定的映射，并且修整是正确的吗？ 请帮我解决这个问题。
