In my API when testing passing traceparent via request headers, the traceparent header was not being picked up and subsequently a new one was being generated.
It appears to be that when __call__ is triggered (Due to a request) in the ASGITracingMiddleware the headers are read as bytes rather than a string and as a result when attempting to match the header name in the headers it will evaulate as false, resulting in None being returned. Here is the code i'm referring to - https://github.com/elastic/apm-agent-python/blob/main/elasticapm/utils/disttracing.py#L142
Not sure if this is intentional or not, and if so if there's any workarounds here, I've not found anything in your docs with regards to configuration at least 🤔
In my API I am using ASGITracingMiddleware for a quart application.
Please let me know if you need anymore information
