java.lang.IllegalArgumentException: Jetty ALPN/NPN has not been properly configured.

I’m trying run a code that use a cloud-vision. Everything works normally when I use my desktop(ubuntu / windows10). But when I use a raspberry appear the following error:

Anyone can help me please?

Unfortunately, Raspberry Pi runs on ARM, but ARM is not a supported architecture for the tcnative dependency of grpc yet. Thus, you won’t be able to use any of the clients in this repo based on gRPC.
