Java Function Node issue

I tried to use the javafunction node by following the example in Node-red website

But I've got this message in the debug window
Could you help me ?

TypeError: this.imports is not iterable


That is not a commonly used node. Maybe best to try to contact the author direct.

At the very least, you would need to share the Java code in that function. That could be a Java error rather than a JavaScript one.

Thank you, I just resolved it.
I updated java version and path variable. I t could be useful for people.
