🐛 Bug Report

Trying to run go install github.com/grpc-ecosystem/grpc-gateway/v2/protoc-gen-openapiv2 to install the protoc-gen-openapiv2 plugin, but I'm thrown back this panic message, along with the stack trace:

Hi, what Go version are you using? I wasn't able to reproduce this error with Go 1.19.3.
