try to use

```auto
       mutate {
               conver => ["type", 'integer']
            }

```

but I got error

```auto

So I have to convert it To string first ,then to interge

```auto
        mutate {
            convert => {"[json][type]"=> "string"}
        }
        if [json][type] == 'true'{
            mutate {
                replace => {"[json][type]"=> 1}
            }
        } else if [json][type]=='false' {
            mutate {
                replace => {"[json][type]"=> 0}
            }
        }
        mutate {
            convert => {"[json][type]"=> "integer"}
        }

```
