Is there something limitation for Cloud Trace on Cloud Run?

Question

I'm building microservices on Cloud Run with Java. So, I want to use CloudTrace for these services. But it doesn't work as I expected. A DeadlineExceededException is raised.

I can run same services on my local PC. And in that time, it's no problem. I can confirm tracing on CloudTrace. But when I deployed them on Cloud Run, Tracing doesn't work... Do you have any idea?

Code is below. I use OpenCensus library.

var spanContext = TEXT_FORMAT.extract(request, GETTER);
var builder = Tracing.getTracer()
        .spanBuilderWithRemoteParent(name, spanContext);

builder.setRecordEvents(true)
        .setSampler(Samplers.alwaysSample())
        .startScopedSpan();

try ( var ss = builder.setRecordEvents(true)
        .setSampler(Samplers.alwaysSample())
        .startScopedSpan()) {
    var span = Tracing.getTracer().getCurrentSpan();
    span.putAttribute(HttpTraceAttributeConstants.HTTP_HOST, AttributeValue.stringAttributeValue(host));
    span.putAttribute(HttpTraceAttributeConstants.HTTP_METHOD, AttributeValue.stringAttributeValue(method));
    span.putAttribute(HttpTraceAttributeConstants.HTTP_PATH, AttributeValue.stringAttributeValue(path));

    // Something logic
}

Error is below.

I tried Extensible Service Proxy. It works. But I want to make the tracing as a part of application.
