Hey,
sorry I haven't been in touch for so long. I just tried to update the mod, but I'm stuck with this error message and have no idea how to fix it: https://prnt.sc/jIjLb_AqyU9l
At this point you can only hope that DE_Schmitt updates his version.
I believe that error means the object is not defined according to 2.0 specifications. So instead of a short, one line array, try using a multi-line object with one property (and "type" property) per line. Let me know how it goes.
