Broken pipe error when reproducing opentelemetry-otlp/examples/basic-otlp locally

[JoseCVM]

Since this example is mostly what I want to do for my application, I tried reproducing it. When I do that, I see this "stream closed because of a broken pipe" error:

OpenTelemetry trace error occurred. Exporter otlp encountered the following error(s): the grpc server returns error (Unknown error): , detailed error message: transport error tonic::transport::Error(Transport, hyper::Error(Io, Custom { kind: BrokenPipe, error: "stream closed because of a broken pipe" }))
Error: Other("[ExportErr(Status { code: Unknown, message: \", detailed error message: transport error tonic::transport::Error(Transport, hyper::Error(Io, Custom { kind: BrokenPipe, error: \\\"stream closed because of a broken pipe\\\" }))\" })]")

I've tried keeping my implementation as close to the example as possible, up to the point where I cloned the entire repo and tried running the example, and this still happens. Am I missing some required setup here? I tried looking for similar issues, but I only found people running into this when trying to user the jaeger collector, which is not the case here - I am using the docker-compose provided in the example.
I also tried running this both in WSL and directly on Windows to the same effect.

Thanks in advance, any help is appreciated

#2180 should fix the example! Once you apply it, the error should be done. If not, please reopen.
