Cannot manage to send String DateType to OPC UA from Http Request - httprequest

Question

Which node-red-contrib-iiot-opcua version are you using?
4.0.9
What happened?
I'm trying to send an HTTP request over OPC UA node, but it's not working at all. The string node never updates.
Server
OPCUA-IIoT-Flex-Server Node (Please attach AddressSpaceScript to the next section)
How can this be reproduced?

What did you expect to happen?
It should update the OPC UA node.
