RealUptime Errors

Browser errors that eat your quota.

Five front-end errors nobody can act on, what each one means, and how to filter it. RealUptime Errors drops all five by default and counts what it dropped.

ResizeObserver loop limit exceededWhy browsers report "ResizeObserver loop limit exceeded" and "loop completed with undelivered notifications", why it is almost never a bug, and how to filter it.Script error.Why error trackers show "Script error." with no message, line or stack, how crossorigin and CORS headers fix it, and when to filter it.Non-Error promise rejection capturedWhy Sentry-compatible SDKs report "Non-Error promise rejection captured with value", where it comes from, and how to fix or filter it.ChunkLoadError: Loading chunk failedWhy "ChunkLoadError: Loading chunk failed" and "Failed to fetch dynamically imported module" spike after deploys, and how to recover instead of erroring.chrome-extension:// errorsWhy stack traces full of chrome-extension:// and moz-extension:// frames appear in front-end error tracking, and how to keep them out.
