Hi @okynos
we can't reproduce it

are you using some particular config or environment?
Does the same response comes from the API through a curl?

Hello @frankeros,

Here you have the API output, Ubuntu return a good addDate but the rest not.
api_agents.txt

I'm using the OVA made by @pacoqack with the last Splunk package app installed Revision 68. I haven't modified any particular config, if you want some more data or the full environment tell me.
