Json_value spitts out warnings and errors

Hi,
i build a custom controller for my led-bow. It litstens to specfic keywords.
And i pass them using the value_json but this causes my system to be instable (or at least i think/hope so)
What can i do to fix this?

This is the error/warning i have been reciving
