AWS X-Ray ID propegation when using opentelemetry-spring-boot-starter

[verbitan]

Hi,

How can I use AWS X-Ray compatible trace ids and propagate them to downstream services when using opentelemetry-spring-boot-starter?

I tried using AutoConfigurationCustomizerProvider but the ID isn't propagating, as you can see below.

@Bean
public AutoConfigurationCustomizerProvider otelCustomizer() {
    return p ->
        p.addPropagatorCustomizer(
                (fallback, config) ->
                    TextMapPropagator.composite(
                        fallback, AwsXrayPropagator.getInstance()))
        .addTracerProviderCustomizer(
                (fallback, config) ->
                    fallback.setIdGenerator(AwsXrayIdGenerator.getInstance()));
}

{
  "method": "GET",
  "protocol": "https",
  "host": "echo.free.beeceptor.com",
  "path": "/test",
  "ip": "xxx.xxx.xxx.xxx",
  "headers": {
    "Host": "echo.free.beeceptor.com",
    "User-Agent": "curl/7.61.1",
    "Accept": "*/*",
    "Forwarded": "proto=https;host=\"test-server:8443\";for=\"192.168.0.100:55254\"",
    "Accept-Encoding": "gzip"
    <--- missing "X-Amzn-Trace-Id" --->
  },
  "parsedQueryParams": {}
}

The documentation shows that we need to configure the following, which I believe I've done the equivalent of using AutoConfigurationCustomizerProvider.

OpenTelemetrySdk.builder()

        // This will enable your downstream requests to include the X-Ray trace header
        .setPropagators(
            ContextPropagators.create(
                TextMapPropagator.composite(
                    W3CTraceContextPropagator.getInstance(), AwsXrayPropagator.getInstance())))

        // This provides basic configuration of a TracerProvider which generates X-Ray compliant IDs
        .setTracerProvider(
            SdkTracerProvider.builder()
                .addSpanProcessor(
                    BatchSpanProcessor.builder(OtlpGrpcSpanExporter.getDefault()).build())
                .setIdGenerator(AwsXrayIdGenerator.getInstance())
                .build())
        .buildAndRegisterGlobal();

Thanks in advance
