Splunk unable to detect color codes

[manojdevaki]

What happened:

I've deployed fluent-plugin-splunk-hec on a Kubernetes cluster and the plugin is adding color codes to the log which is not being detected in Splunk

What you expected to happen: color codes should be removed

Actual Log:
2023-02-08T13:35:44.818Z - info: ::ffff:127.0.0.1 - GET /v4/ping HTTP/1.1 200 578 - 0.953 ms

Log as shown in Splunk:
2023-02-08T13:40:45.697Z - [32minfo[39m: ::ffff:127.0.0.1 - GET /v4/ping HTTP/1.1 200 578 - 1.316 ms

How to reproduce it (as minimally and precisely as possible):
