Syntax errors in PlantUML plugin

[Adam]

Hi,

I have PlantUML plugin in my Confluence with "Version: 6.26 by avono AG", I am newbie in usage of this feature.

I try to use it with several functionalities (like described in https://avono-support.atlassian.net/wiki/spaces/PUML/pages/9699367/Macro+plantuml.)

for example: if I try to paste first Sample code into my plugin I have an error 

, if I try to paste the following content: 

@startjson
{
"fruit":"Apple",
"size":"Large",
"color":"Red"
}
@endjson

into plugin then I have another kind of error 

Is this my fault ? Or maybe different version of my plugin regarding to the documentation, or ... I dont know. Could you explain me what is wrong ?

Best Regards
