nit: I think the function name is a bit misleading, there's no error passed as parameter, also the function is not reused anywhere. I think I'd prefer to get rid of the function and just put the code directly in WriteJSONToResponse

Thanks for the suggestion. function WriteErrorToDefaultLogger is now integrated into function WriteJSONToResponse from line 84 to 86.

would it be better to have if httpStatusCode<200 || httpStatusCode>299 ?

As httpStatusCode 1xx and 3xx would not be considered as an error code; therefore the if statement httpStatusCode >= 400 && httpStatusCode <= 599 is used here to only propagate httpStatusCode 4xx and 5xx to the agent log.
