Hello!
There's a few new parameters added from version 1.3 to 1.6.3. The error you're getting is probably because some of them might not be set. I believe you just need to open the JSON config parameters, so the plugin can load default values for the new parameters, then save your settings and give it another go.
From the console error message it seems the crash is occurring because the plugin is trying to access specifically the parameters that defines which object inside your JSON describes the variable and visible text arrays. Having those parameters updated in the Plugin Manager should fix that!
