Summary: Ok so this is a doozy. ## Overview There was a report that some console.error calls were being shown as warnings in LogBox but as console.error in the console. The only time we should downlevel an error to a warning is if the custom warning filter says so (which is used for some noisy legacy warning filter warnings internally). However, in when I switched from using the `Warning: ` prefix, to using the presence of component stacks, I subtly missed the default warning filter case. In the internal warning filter, the `monitorEvent` is always set to something other than `unknown` and if it's set to `warning_unhandled` then `suppressDialog_LEGACY` is always false. However, the default values for the warning filter are that `monitorEvent = 'unknown'` and `suppressDialog_LEGACY = true`. In this case, we would downlevel the error to a warning. ## What's the fix? Change the default settings for the warning filter. ## What's the root cause? Bad configuration combinations in a fragile system that needs cleaned up, and really really bad testing practices with excessive mocking and snapshot testing (I can say that, I wrote the tests) ## How could it have been caught? It was, but I turned off the integration tests while landing the component stack changes because of mismatches between flags internally and in OSS, and never turned them back on.
