How to query the production environment logstash report error parsing JSON

1. Some errors are reported in the production environment

The information is as follows:

2021-10-15T15:49:28,932][WARN ][logstash.filters.json    ][main][7e17a3dc7e2c6df08ed7012ca6bfe17e3277d05d745f2c5bf55d2b01b151e25b] Error parsing json {:source=>"message", :raw=>"查询用户详情接口", :exception=>#<LogStash::Json::ParserError: Invalid UTF-8 start byte 0x9f

2. Processing method
this is because the log is not printed as required during processing. We need to open a new logstash to print the abnormal log
the configuration is as follows:

[[email protected] conf.d]# more aName1.conf 
input{
    kafka{
           bootstrap_servers => "10.152.17.50:9092"
           group_id => "gt-scs-log-new"
           topics => "gt-scs-log"
           consumer_threads => 1
           decorate_events => true
           auto_offset_reset => "latest"
           type => "gt-scs"
    }
}
filter {
    if [type] == "gt-scs" {
      mutate { 
                add_field => { "types" => "%{type}"}
             }
      json {
                source => "message"
          }
      json {
                source => "message"
          }

    }
}
output { 
  if [tags] { 
        stdout {
                codec => "rubydebug"
        }
  }
}
