Error in which path 'StreamOrderbookUpdates' does not exist in v4-proto-js

[2hyunbin]

I created the full node grpc streaming client using v4-proto-js.
But with all the other commands is normal, only StreamOrderbookUpdates gets the unknown path, unknown request error. What's the problem?
(The first two are normal, and the other two are errors)
