Running Project with `rebar3`

1. Application will running on Port :8083

2. run `Nginx` at port `:4317` to mock OTLP Collector

3. When Visit `GET /` Endpoint should sent Opentelemetry to Configured Endpoint

4. [Alternative Debugging] run `docker-compose up` then you should have real OTLP collector running at port `gRPC:4317` too (I had already tried but it didn't work)

#### Expected Bahavior

Erlang Application should sent Traces with `:POST` method to Nginx but currently it didn't work for both GRPC and HTTP

#### Running Local Project

This command will give you successful connect with Open Telemetry

```

rebar3 shell

docker run -p 4317:80 docker.io/nginx

```
