Io.opentelemetry.api.internal.AutoValue_ImmutableSpanContext невозможно привести к классу co.elastic.apm.agent.opentelem ⇐ JAVA

[Anonymous]

I'm running a Temporal workflow. and I need to send APM tracing to ELK stack (Elastic)

Elastic provides a java agent elastic-apm-agent to send APM tracing logs to ELK's APM server.

As per my understanding elastic-apm-agent uses OpenTelemetry for tracing. But Temporal uses OpenTracing. So I used a bridge OpenTracingShim for trace/context propagation.

But when I run my workflow it gives following exception
