Hello, I’m back with another question. I have successfully connected to my remote Stardog server and am able to create and initialize a Repository and a RepositoryConnection. I can use the AdminConnection.list() method to see my databases successfully, so I know that the connection worked to some degree. I am also able to successfully query the database using the RepositoryConnection.prepareBooleanQuery() method. So it seems that most Read operations are a go.
However, I have been unable to load data into the database. Here is the code I am using:
val repo: StardogRepository = new
StardogRepository(ConnectionConfiguration.to("myDB").server("http://myIP:myPort").credentials("admin", "admin"))
repo.initialize()
val cxn: RepositoryConnection = repo.getConnection()
val f: ValueFactory = cxn.getValueFactory()
RepositoryConnections.add(cxn, new File("synthesized_300.ttl"))
The last line is the one which causes the following error:

Any thoughts on how I can go about debugging? I thought that it might be some sort of security setting on my database, but my admin user seems to have full privileges.
