While creating connection to MDM repository using MDM JAVA API

Question

I am getting the following error message:
Unexpected field type 28
I am able to debug that this error message is being displayed after executing the following line of code:
/** Get the Repository schema */
GetRepositorySchemaCommand repositroySchemaCommand =
new GetRepositorySchemaCommand(simpleConnection);
repositroySchemaCommand.setSession(repositorySession);
repositroySchemaCommand.execute();
Now can anyone please explain how to resolve this error?
Thanks in Advance.
