Xml webservice "Type {http://dom.w3c.org}Node is referenced but not defined."

I’m testing Lucee version 4.5, and I’m getting this errors:

Invoking page:

Ciao Xml!

is struct? #isStruct(argXml)# <!— yes —>

Beside interpreting the Xml doc as a struct, I get the error pointed out in
the subject: Type {http://dom.w3c.org}Node is referenced but not defined.

Thanks for any suggestion
