how do you get rid of the [0] "\_jsonparsefailure?

```auto
{
                 "origin" => "some_platform",
              "ls-source" => "some_platform",
                   "port" => 1234,
                  "event" => {
        "severity" => 1
    },
               "@version" => "1",
              "breachUrl" => "",
                   "time" => 1645739629935,
                   "tags" => [
        [0] "_jsonparsefailure"
    ],
           "creationTime" => 1645739629935,
    "triggeredComponents" => [
        [0] {
            "triggeredFilters" => [
                [0] {
                           "trigger" => {
                        "value" => "Test filter value"
                    },

```

If it is getting added by a json filter then you can prevent that using `tag_on_failure => []`. To remove it you could use

```
mutate { remove_tag => ["_jsonparsefailure"] }
```

what would be the causation of this error? where could I look?

I have one now with \_mutate\_error as well, but currently doing this.

```auto
mutate { remove_tag => ["_jsonparsefailure" ,"_mutate_error"] }
```

The json filter or codec will have logged "exception=\>#\<LogStash::Json::ParserError:" with a more specific error message in the logstash log.
