This three issues I am having:

1. https://github.com/influxdata/telegraf/actions/runs/11541885708/job/32124423506?pr=16081 I am highly confused. I ran super-linter locally and only issues I got are MD013 which are according to .markdownlint.yml shall be ignored.
2. https://app.circleci.com/pipelines/github/influxdata/telegraf/23202/workflows/acca2f7b-af70-4cc2-a827-736c98f95542/jobs/362160 This one looks like something not working properly. The script make_docs.sh when running locally formatting telegraf/plugins/outputs/wavefront/README.md so I believe it is the reason for the failure
3. https://app.circleci.com/pipelines/github/influxdata/telegraf/23202/workflows/acca2f7b-af70-4cc2-a827-736c98f95542/jobs/362162 not seems to be related at all

#16087 I believe should fix the first two, and the 3rd is an unrelated flaky test, so nothing needed here (other than a rebase/merge after the linked PR merges)

Thanks @s-r-engineer for your contribution! I want to encourage you to simplify your code! Why not defining known tag and field names of responses and decode the JSON responses to map[string]string? Then you can iterate over the map and decode the value accordingly? This would get rid of the reflection code and in general would simplify the code...

@s-r-engineer my review comments are that, comments about the code. They are not meant to criticize or insult you as a programmer or anyone else. If you understood it this way, please accept my apologies.

@srebhan I never was insulted whatsoever. I am sorry if I made you feel like that.

[s-r-engineer]

@srebhan what to do with this? I am not sure why this is an issue. https://app.circleci.com/jobs/github/influxdata/telegraf/363717
