Error with OpenTelemetry Span Processor in Effect Typescript Library Example

i'm struggling to get otel traces logged anywhere outside of the console. when i follow the example https://effect.website/docs/observability/tracing/#tutorial-visualizing-traces-with-docker-prometheus-grafana-and-tempo directly, without alteration, i get the following error:
