I submitted a change through OpenConfig to configure the BGP RIB, however, a NPE was thrown immediately. It even happens after I restart on controller.

It was possibly due to I deleted the BGP RIB configuration via OpenConfig API during the test. But it still happened after I put the RIB configuration back via OpenConfig.
