When I configure a multipath route according to the postman (included) and I GET operational data for the route, the response is code 500 error, and the log shows:

ReadFailedException: Failed to read...static.routes.ipv4.Route[key=RouteKey [_id=0]]

...

IllegalStateException: Unexpected size of list: []. Single item expected.

Notes:

Also affects IPv6 multipath in the same way.

Does not happen on 17.07.

Likely caused by a VPP change between 13th and 21st July in 17.10
