title: How to let fluent-bit skip the field that can not be parserd?
body: <p>I am trying to send data from fluent_bit to the Elastic search
  Here is my fluent-bit parser:</p>
  <pre><code>[PARSER]
      Name   escape_utf8_log
      Format json
      # Command      | Decoder     | Field | Optional Action
      # =============|=====================|=================
      Decode_Field_As  escaped_utf8   log
      Decode_Field         json       log [PARSER]
      Name   escape_message
      Format json
      # Command      | Decoder | Field | Optional Action
      # =============|=================|=================
      Decode_Field_As  escaped_utf8   message
      Decode_Field         json       message
  </code></pre>
  <p>Here is my fluent-bit config:</p>
  <pre><code>[FILTER]
      Name         parser
      Match        docker_logs
      Key_Name     message
      Parser       escape_message
      Reserve_Data True
  </code></pre>
  <p>In some cases, other people would put the log data to the fluent-bit in the wrong format so that we can get &quot;mapper_parsing_exception&quot; (example: filed to parse field [id] of type long in document).</p>
  <p>I am trying to skip parsing a log and then send it to ES anyway if the fluent can not parse that log. so that we would not get the parser error even if someone sends the wrong format to fluent_bit.  Is this possible to do that?</p>
