Themes and plugins are causing lots of “FA icon deprecation” warnings:
and I have seen two different kind of responses to this: “don’t worry it’s just a warning” and “if you want to get rid of them, just fix the theme or plugin” (which is not always easy).
So, let’s just ignore those warnings. Or… as it turns out… these warnings are frequently causing 429 rate limit errors and our logs are full of
Would it be possible to well, rate limit those warnings on the client, so they don’t trigger all those requests? Or exempt POST /logs/ from rate limiting?
You should replace the deprecated icons, that will remove the log entries and the post requests to /logs entirely. Plus, the old name fallbacks will be gone very soon (i.e. next few weeks).
Ok, I found something. This is not the problem @DaveK was having though.
They are indeed rate-limited, but Logster rate-limits them even further, at one per minute per IP, resulting in 429 errors when there are multiple deprecation warnings in a single page load.
This actually causes deprecation warnings to get lost, making the /logs less valuable as a tool to find all deprecations…
a 1 minute rate limit to all JS error reporting per IP
