Bug Report

We recently upgraded the datadog gem to version 2.15.0 and switched from the Datadog integration provided by Karafka to the one provided by the gem.

We noticed that when a span with the karafka.consume operation encounters an error, it is not propagated to the parent span, like in the screenshot below. We correctly see one operation per Kafka message but the parent span with the worker.process operation looks like no error was detected.

For comparison, this is how the same error used to appear with the integration provided by Karafka:
