Can't create a scan config (failed to find config)

Hello,
I have just installed the last version Kali Linux and OpenVAS. I can’t create scan config, I have current status feed, but my last logs show
libgvm util:Warning(date) ERROR: Error on line 1 char 1: Document was empty or contained only whitespace
md manage:Warning:(date) update_nvt_cache_osp: failed to get VTs

Do you know what is the problem ?
