Hi,
We're having an error reported in the Monitoring tool related to a null value in the source parameter
2022-02-10 11:05:03.102: Value cannot be null. Parameter name: source. System.ArgumentNullException: Value cannot be null. Parameter name: source

2022-02-10 11:05:03.122: Request headers: [ "Host", "User-Agent" ]
2022-02-10 11:05:03.122: Request item keys: [ "ExecutionTableMapper", "Dynamicweb.Environment.Web", "owin.Environment", "AspSessionIDManagerInitializeRequestCalled" ]
2022-02-10 11:05:03.122: Request form: []
The odd thing is that I would expect this error to be reported every single time the request happens, but that's not the case. So I am confused why this happens sometimes.
Does anyone know why?
Best Regards,
Nuno Aguiar
