I got an type error Cannot read property 'forEach' of undefined when I run my node. Can someone give me some advice please?
Can you provide more details, such as the full error message and the stack trace from the log?
Are you developing your own node here? That error can be caused if you have a node that's missing its .html file.
yes. I'm making a new node. But I have the html in the file folder.
Point us to the GitHub repository where the node is.
If you haven't set that up yet then do it. You can always delete it again later if you discard the node.
