Unable to filter out exceptions using "ITelemetryProcessor" in Azure Web API

Hi,
I have a Azure Web API were I try to ignore a specific exception from being shown in Application Insight:

In order to do so, I need to inspect the exception message that is related to the exception being thrown (defined in the "ReasonPhrase"):

My problem is that the code logic for "ExceptionTelemetry" never seems to be executed.
Here is my implementation of the ITelemetryProcessor:

I need the code line marked in yellow to be hit, but it seems that I never get any "ExceptionTelemetry".
NB! When I run the code locallly, I see that other types of telemetry data is fetched (like "RequestTelemetry" etc.) So the ITelemetryProcessor seems to trigger at least, but not on my specific exception...

Any tips on what I need to do to achieve this?

Regards,
