Im using fluentbit to scrape logs and send it to logstash. logstash forwards it to ES.  
i already have a field with kubernetes.labels.app on a separate event(production)  
I am using helm for my development event and helm creates the labels with dots for eg: [app.kubernetes.io/instance](http://app.kubernetes.io/instance).  
As you can see the error i get in the title. it doesn't like that the mapping already exists and is of different type.  
I have tried renaming the labels using mutate filter in the input section of the fluentbit config file but that does not help. i also tried the de\_dot filter.  
any workaround for this like the way you have for beats using drop\_field processors?
