I have everything running in a docker container with the following version: nodered/node-red:3.0.2
What can be wrong? I can't find much documentation with examples of how to use it correctly, or maybe I'm not looking for it right.

Hi @WilsonOviedo - Welcome to the forums

I'm not sure of any prerequisites in using this node (assuming all required libs are installed)
but your code seems fine - You will need to raise this issue with the author of the node.

Hi, @marcus-j-davies, thaks
There is no mention of any prerequisites to install it. I will make your suggestion, I will ask the author.
Thank you very much for your answer.
