Krakend DEbug Log

[Nitin Suryawanshi]

Hi,

We are using Krakend API Gateway Version 2.0.0.  for logging we have developed a custom pipeline with the following configuration in the krakend_template .json

"github_com/optivainc/optiva-product-shared-krakend-telemetry": {

            "logging": {

                "level": "{{ env "LOG_LEVEL" }}",

                "module": "[OPTIVA-OBP-RTS-APIGATEWAY]",

                "skip_paths": ["/__health", "/healthz/readiness/appCrm", "/healthz/readiness/appCrmHome", "/healthz/readiness/esb", "/healthz/readiness/ocg", "/healthz/readiness/vra", "/healthz/readiness", "/healthz/readiness/auth", "/healthz/readiness/zammad" ],

                "json": {

                    "disable_html_escape": false,

                    "data_key": "datakey",

                    "pretty_print": false

                }  

            },

When we enable the "DEBUG" log we are getting these null characters in  the logs, although API request and response is correct.

Any out of the box configuration which could help to fix this issue or any other solution to fix this is appreciated,

Hello Nitin,

It is hard to help on a component that Optiva developed, is not open-sourced, and neither KrakenD or the KrakenD community wrote openly. This is a forum for open source usage of KrakenD component, so I do not know how we can be of any help. You might ask the developer of such a component for advice.

Best regards.
