---------------------------------------
Summary: Baggage customization doesn't seem to work
Key: CAMEL-23564
URL: https://issues.apache.org/jira/browse/CAMEL-23564
Project: Camel
Issue Type: Bug
Components: camel-opentelemetry
Affects Versions: 4.20.0
Reporter: Magnus Ekstrand
We are trying to use the Baggage Customization feature introduced in Camel
4.20, but can't seem to get it to work.
We use the OTEL Agent with MDC Instrumentation to have trace_id, span_id and
baggage included in the logs. It works as
expected for our vanilla Spring Boot applications.
For our Camel routes, only externally provided baggage (i.e. an incoming
baggage header) shows up in the logs, but baggage
entries added using a Camel OTEL_BAGGAGE_ header as described in
[https://camel.apache.org/components/next/others/opentelemetry2.html#_baggage_customization]
does not show up in the logs.
Our route looks like this:
{code:java}
from(..)
.setHeader("OTEL_BAGGAGE_BusinessReference", header(REFERENCE_HEADER))
.process(logReceived) // <- logging happens in here
.process(transformer) // <- logging happens in here
.to(..)
.process(logSent); // <- logging happens in here
{code}
An incoming baggage entry is included in the logs, but not the
BusinessReference entry.
What am I doing wrong?
