Runtime error: invalid memory address or nil pointer dereference

[dmumladze]

Any reason I should be getting this error? I have the latest Go and grpcui, but getting this weird error. There are no local imports in my proto and btw, I can connect and use Postman without any issues.

grpcui -vvv -plaintext -proto ./grpc/Model.proto localhost:8009

[jhump]

Dang. Looks like the same thing as fullstorydev/grpcurl#414 (and jhump/protoreflect#572). Sorry for the breakage, my bad.

There's a fixed release of protoreflect (v1.15.3), so this repo needs the same fix that was already made in grpcurl.
