Rogue Parent ID generate in Azure Container App

Describe the issue you're reporting

I have written a simple API based on the scaffolded weather app API.

Scenario 1: I have the API running on my laptop, using Swagger Docs to call the end points that calls an Azure SQL Database to get the weather forecasts and exporting the telemetry data to an OTel Collector Contrib running in an Azure Container App with the ingress set to accept traffic from anywhere. The span collected does not have a Parent ID for the InstrumentationScope Microsoft.AspNetCore section.

Scenario 2: I have the same API running in an Azure Container App within a secure VNet. I use an APIM to call the API endpoints and it uses the same Azure SQL Database to get the weather reports. It exports the Otel data to a collector in an Azure Container App running in the same VNet. The span collected in this environment has a rogue Parent ID in the InstrumentationScope Microsoft.AspNetCore section that is not included in the Otel data.

What could be causing Otel libraries to think there is a parent span that it is not including in the data?

OTel Console output for Scenario 1:
