Hello everyone,

I am trying to visualize a timelion and this is the query i am using:  
**.es(index=investigation\_master\_index,timefield=uco-observable:sentTime.@value,split=uco-observable:messageText.keyword:1000)**

the messageText has data inside as well as the sentTime and i just want to visualize their correllation. What does VALUE\_NULL mean, does it mean that the uco-observable:messageText.keyword doesnt exist? or that it is empty? I have looked everywhere for this and found nothing unfortunately. Maybe the solution is something simple, that I cannot think right now.

Thank you!

Hey @ebosdev, which version of kibana do you use?  
The problem here I think is the `:` in the field names. This was fixed in 7.13. Here is the PR [[Timelion] Fixes bug with escape colons in field names in the metric/split parameter by Dmitriynj · Pull Request #96770 · elastic/kibana · GitHub](https://github.com/elastic/kibana/pull/96770) that made this fix.
