run grpcui and got "Symbol not found: grpc.health.v1.Health"

[plong009]

hello,
I run grpcui 1.0.0 release on Windows and it failed.
E:>grpcui.exe -plaintext 127.0.0.1:50051
Failed to compute set of methods to expose: Symbol not found: grpc.health.v1.Health

but there is a grpc.health.v1.Health service, grpcurl can list it out.
E:>grpcurl.exe -plaintext 127.0.0.1:50051 list
grpc.health.v1.Health
grpc.reflection.v1alpha.ServerReflection
my_grpc.my_grpc_service

the service is wroten c++, almost same as the grpc example greeter_server.cc,
does anyone known how to resolve this issue?
thank you!

looks like it's grpc.health.v1.Health issue, grpcurl also can't list methods.
E:>grpcurl.exe -plaintext 127.0.0.1:50051 list grpc.health.v1.Health
Failed to list methods for service "grpc.health.v1.Health": Symbol not found: grpc.health.v1.Health

sorry,
please close the issue.

@plong009, can you take a look at #40 and see if the suggestion there helps? The issue observed there was that a linker optimization discarded some of the data that is needed at runtime for reflection to work properly. That issue indicates linker options when building the C++ server that may help.

This is a duplicate of #40. Also, I believe it is fixed as of #160 as thus fixed in the next release.

I think it's possible that the root cause was the server's reflection implementation providing unexpected extra files in the response, and the reflection conflict making incorrect assumptions about the order of those files. Also see jhump/protoreflect#466.
