Hi Alex,
I can connect to your server and create and EDM for the the DB.BEWARE.* tables.
It is not clear however how you are executing the sample code to get the error
reported, thus can you please provide the step to reproduce from an empty
project.
Also, can you trying enabling the CallStackOnException parameter in the
Virtuoso ini file, and restart the server to see if an call stack errors are
returned to the client as detailed at:
