AppInsights TelemetryClient throws exception

Question

I am getting the following exception in ASP.NET core mvc application when deployed in docker (ubuntu) in Azure.

System.ArgumentException: The specified configuration does not have a telemetry channel. (Parameter 'configuration')
at Microsoft.ApplicationInsights.TelemetryClient..ctor(TelemetryConfiguration configuration)

I have added the following piece of code in the startup.cs

services.AddSingleton(typeof(ITelemetryChannel), new ServerTelemetryChannel());  
        services.AddApplicationInsightsTelemetry();  

Can you please guide me why this error is occuring? Its working perfectly in development environment when run from VS

Answer 1

It could be a bug of Microsoft.ApplicationInsights.AspNetCore version 2.17.0.
If you update to the latest version it should disappear.
