I tried to run sample code for openconfig BGP and got the below error, this error received even when run the same sample code from vagrant virtual vm

This is known issue in openconfig Yang models, which uses non-standard string pattern regular expression. See https://github.com/openconfig/public/issues/175 for details. It is not clear for how long it is going to take for Google to fix the models, it might not happen at all. Therefore, please use Cisco native models in your application. Another option would be download openconfig models, manually fix all the pattern definitions and generate YDK bundle.

Many thanks for your support, I fixed for bgp and it is working fine, below link for the fixed yang, json, and source distribution.
