TypeError: The "options" argument must be of type object. Received an instance of Array

Hi,
When I run the examples of machine-learning-v2

https://github.com/hbouvier/node-red-contrib-machine-learning

after deploying, the debug window showed error:
TypeError: The "options" argument must be of type object. Received an instance of Array

My Node-RED is running on windows,(also tried on linux, the same error).

node --version v16.16.0
Node-RED version: v3.0.2

Does anybody know the problem?

The node has not been updated in 4 years or so, and neither this version or the one it is forked from seem to be active.

It seems you are not the only one with this issue

Hi @smcgann99

Thank you for your reply.
Yeah, it's strange.
