Hi there,

I am trying to send ExtensionObject datatypes using the lastest version of node-red-contrib-opcua.

Does anybody know if this node supports writing this datatype?  
(I've tried with other datatypes such as boolean and I could manage to do it)  
If so, what format should the payload have?

Thank you,

---
