dd-trace traces not supported

[lbennett-stacki]

I have initialized the dd-trace tracer and registered vercel otel instrumentation in my app router instrumentation hook. I can see nextjs APM traces coming through to datadog, but any cases where I use the datadog tracer to create custom spans etc do not seem to work.

i.e. Built in, automatic spans, for "executing api route X" and outbound requests are traced. But my custom dd-tracer.startSpan('yada', ...) are not being traced.

Hi @lbennett-stacki! dd-trace and @vercel/otel are not supposed to be used together.

Can you share more details:

• What are you trying to achieve?
• Is the app hosted on Vercel or some other platform?

Hi there, also looking for this functionality. Specifically to connect dd-trace llmobs to vercel ai sdk as sending the ai sdk telemetry data directly to datadog as an attribute results in the span attributes being truncated.

Notably, we can use the datadog auto-instrumentation but the resulting traces are not being associated with their parent spans.

The app in question is hosted on vercel.
