如何在logstash中过滤jsonb object

Question

如果在将过滤器应用于 json 类型后对其进行变异，我希望它会成为过滤器。

我正在使用 jdbc 输入

postgres some_column 类型是 jsonb 类型

数据集

some_column: {
  id: 1,
  type: "some",
  name: "name"
}

我试图

filter {
  json {
    source => "some_column"
  }

  mutate {
    add_field => {
      "[some_column][name]" => "some_column_name"
      "[some_column][id]" => "some_column_id"
    }
    remove_field => ["some_column"]

  }
}

Logstash 抛出这个错误

Sep 24 08:20:05 ip-172-31-39-95 logstash[60415]: [2022-09-24T08:20:05,028][WARN ][logstash.filters.mutate  ][main][6b5bfecfc90257b9d235f6af6be2c9cef079a5ab89f59bf98b51f017841e4465] Exception caught while applying mutate filter {:exception=>"Could not set field 'name' on object '' to value 'some_column_name'.This is probably due to trying to set a field like [foo][bar] = someValuewhen [foo] is not either a map or a string"}

我只想在 json 字段中保存必要的值并删除 some_column 字段，我该怎么做？
