I have a class in dependencies and have not been able to figure it out by combing through various GitHub issues. This is my error:
These are my deps:
That error means that grpc is using it’s own version/fork of cowboy that can be found at: GitHub - elixir-grpc/cowboy: Small, fast, modern HTTP server for Erlang/OTP. · GitHub
If you manually override cowboy in your deps it’ll hopefully work (but it depends on the changes that grpc made):
{:cowboy, github: "elixir-grpc/cowboy", tag: "grpc-2.6.3", override: true},
