Errors loading plugin {grpc_plugin, "~> 0.7.0"} when running rebar3 as test shell

[RyandenOtter]

I pulled the latest version of the repo, and ran the rebar3 as test shell as instructed in the documentation. I am getting this error:

ryan@Ryans-MBP grpcbox % rebar3 as test shell DEBUG=1

The erlang version that I have installed is 23.2.7

Is there some dependency that I am missing?

Also, when I hit localhost:8080, I get this crash report:

@RyandenOtter I got the same error, and upgrading the locale rebar3 version helps
