Problem with Node-Red Machine Learning

General
1

Hello together,

I want to gain some experience concerning machine learning. Therefore I tried the NR example:
node-red-contrib-machine-learning-v2, but I cant get the first part of the flow working. I receive always the errormessage: "TypeError: The "options" argument must be of type object. Received an instance of Array"
I tried to solve it with Chatgbt, but without success.
Here is the flow:
