Error when communicating the server

[Vecnir]

Hello.

I created workflow, based on workflow i found on youtube (OpenKM channel) and i have an error:

Any ideas/suggestions?
Or even questions! I don't know what to describe, and i apologize for that.

I've got hibernate set to "none".

I connect to OpenKM locally, by default path localhost:8080/OpenKM.

Should take a look at catalina.log in order to see complete stack trace log ( post here the complete log error and will be able to give you some idea about what happens ).
