Http 413 error in Kong is not getting forwarded to new relic


Basically while giving a large payload it’s getting checked in the Kong side and as because of this parameter client_max_body_size 500k getting error in the Kong side. But unfortunately, this error is not getting reported to the new relic dashboard.
giving the error log details:

I am having this configuration in nginx-kong.conf.
error_page 400 404 408 411 412 413 414 417 494 /kong_error_handler
All other error except the 413 is getting reported to the new relic. Please guide me in this.

@hbagdi Sir if you can suggest anything here.
