In general i am not sure how to get telemetry working with Spin v3.6.2. After trying to use to otel plugin, i switched to directly running jaeger:

docker run -d --name jaeger \
  -e COLLECTOR_OTLP_ENABLED=true \
  -p 4318:4318 \
  -p 16686:16686 \
  jaegertracing/all-in-one:latest

I am getting this error:

2026-04-02T22:31:14.767965Z ERROR opentelemetry_sdk:  name="PeriodicReader.ExportFailed" Failed to export metrics reason="Operation failed: reqwest::Error { kind: Status(404), url: \"http://localhost:4318/v1/metrics\" }"
