It does render despite the error messages. And yes, I am using
"--use-offscreen-rendering"
Thanks

Rick,
Are you simply getting the error message or it even fails to render?
There's some issue (which I will look into hopefully soon) which results
in that error message, but that should not affect the actual rendering.
Also just to confirm, you are using the --use-offscreen-rendering
command line option on the server.
