 The request uses binary protobuf to encode the payload, so you need to use packages that support `HTTP/protobuf`. For example, in Node.js, you can use [`exporter-trace-otlp-proto`](https://www.npmjs.com/package/@opentelemetry/exporter-trace-otlp-proto); in Go, you can use [`go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`](https://pkg.go.dev/go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp); in Java, you can use [`io.opentelemetry:opentelemetry-exporter-otlp`](https://mvnrepository.com/artifact/io.opentelemetry/opentelemetry-exporter-otlp); and in Python, you can use [`opentelemetry-exporter-otlp-proto-http`](https://pypi.org/project/opentelemetry-exporter-otlp-proto-http/).
