Hi @vjineo Welcome to the community. What version are you on? Looks like a duplicate of this... Please be patient new users it take a few minutes for topics to show up. I will close that one. > [@Filebeats NetFlow: Events dropped due to out of range of long value](https://discuss.elastic.co/t/filebeats-netflow-events-dropped-due-to-out-of-range-of-long-value/377375): > > Most of the events are dropped with below error: {\"type\":\"document\_parsing\_exception\",\"reason\":\"[1:1475] failed to parse field [netflow.flow\_id] of type [long] in document with id 'M7a4XZYB\_Zr7jpsbS6pn'.

But Fi… Ohhh I think you will need to set that to keyword, I see on the other modules it is set to `keyword` ```auto - name: flow_id type: keyword ``` It might be worth opening an Issue.... > **[beats/x-pack/filebeat/input/netflow at 66e172ca24ec82f07bcd89da7436479a6e6c20f1...](https://github.com/elastic/beats/tree/66e172ca24ec82f07bcd89da7436479a6e6c20f1/x-pack/filebeat/input/netflow)** > > :tropical\_fish: Beats - Lightweight shippers for Elasticsearch & Logstash - elastic/beats --- _[View the full topic](https://discuss.elastic.co/t/netflow-flow-id-data-type-incorrectly-set-to-long-instead-of-unsigned-long/377377)._
