As of the latest iotivity-node, security is enabled. Therefore, for successful communication between the client and the server, you need to create oic_svr_db.dat files for both the client and the server. The process and links to sample files can be found at https://wiki.iotivity.org/security_resource_manager
You create the files by processing a JSON file using json2cbor, a tool provided by iotivity. You can build the tool as part of iotivity with
scons SECURED=1 resource/csdk/security/tool
You need to place the resulting .dat files into a subdirectory of ~/.iotivity-node
The name of the subdirectory is the sha256sum of the absolute path of the JS file. So, for a file named "/home/user/project/server.ocf.js", you can obtain the sha256sum as follows:
echo -n '/home/user/project/server.ocf.js' | sha256sum
This yields
ff85509781006eb0da9c4e278e1a685d9b55e09bb03f4115d07fbe6a92d4569e -
Thus, you would
mkdir -p ~/.iotivity-node/ff85509781006eb0da9c4e278e1a685d9b55e09bb03f4115d07fbe6a92d4569e
and
cp oic_svr_db.dat ~/.iotivity-node/ff85509781006eb0da9c4e278e1a685d9b55e09bb03f4115d07fbe6a92d4569e
After repeating this process for both the client and the server, and having made sure that the files have the correct contents, you can launch the server.
https://github.com/otcshare/iotivity-node/blob/master/SECURITY.md also contains these instructions.
There is a second approach to creating the .dat files. If you take this approach, you provide the server with a sample .dat file, after which you provision it using the iotivity provisioning client example tool. This approach is described here: https://github.com/otcshare/iotivity-node/blob/master/js/README.md

I added console.log into iotivity.OCCreateResource(), but I find no information output.
