Invalid header name [X-B3-TraceId] when WebClient requests with HTTP2 and OpenTelemetry B3Propagator tracing options

[489_LEE_KY]

Hello everyone,

I am getting the "Invalid header name [X-B3-TraceId]" exception when the WebClient request a same URL for second time. The WebClient is configured with HTTP2 and OpenTelemetry with B3Propagator.

The HTTP2 protocol requires all the headers to be in lower case. First WebClient request able to convert the tracing propagator headers to lower case, however the WebClient failed to do so on second request onward?

Here are my codes:

And the exception stack trace:

Thanks.

Hi,

Thank you for your report.

This looks like a Vert.x core issue related to the tracer integration in the HTTP Client. Would you mind filing an issue to https://github.com/eclipse-vertx/vert.x ?

Thank you
