Hello  
I tried to use the javafunction node by following the example in Node-red website [node-red-contrib-java-function (node) - Node-RED](https://flows.nodered.org/node/node-red-contrib-java-function)

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.
