Missing traces with @vercel/otel

If you are using Next.js, please use a manual OpenTelemetry setup via the NodeTracerProvider than via registerOTel from @vercel/otel. This is because the @vercel/otel package does not yet support the OpenTelemetry JS SDK v2 on which the @langfuse/tracing and @langfuse/otel packages are based.

If you are still missing traces, please see the documentation on serverless environments
