Exception Flood Suppression

exception-flood-suppression

Exception capture is misconfigured to report every event, so noisy or non-actionable errors get sent externally and overwhelm monitoring; selective filtering via init/before_send and ignore options is needed to suppress useless reports.

MATCHESSolution

Remove the catch handlers or re-throw the error after handling it so useMutation can trigger onError

MATCHESSolution

Set options.MinimumEventLevel = SentryLevel.Fatal for MAUI logging events, and check evt.SentryExceptions.FirstOrDefault()?.Handled to drop handled exceptions

MATCHESSolution

use the `ignoreErrors` option — https://docs.sentry.io/platforms/javascript/configuration/filtering/. Tension: Sentry.init({ ignoreErrors: [ "Can't find variable: gmo" ], });. Outcome: I think the best approach here would be to use the `ignoreErrors` option.

MATCHESSolution

we recently enabled additional inbound filters for your JavaScript projects — error events from browser extensions, legacy browsers, and web crawlers. Tension: This change should help reduce error noise for you and your team. Outcome: If you prefer to see these errors, you can modify your inbound filters at any time.

MATCHESSolution

And HTTP Client errors (if you're using `HttpClient` or `HttpClientFactory`) — On ASP.NET Core. Tension: you just need to opt-in. Outcome: options.CaptureFailedRequests = true;.

MATCHESSolution

alerts you on new issues — It aggregates events with fingerprint (by default based on stack trace) into 'issues'. Tension: focused on capturing the most amount of types of errors your app can have. Outcome: You can configure alerts of course for other conditions beyond new issues.

MATCHESSolution

try reducing Sentry's http_connect_timeout and http_timeout options — If you do need it, and slow connections happen randomly. Tension: slow connections happen randomly. Outcome: Sentry\init([ 'http_connect_timeout' => 2, // The default is two seconds. 'http_timeout' => 5 // Reduce these values and test if Sentry still sends events. ]);.

MATCHESSolution

// Override console.error — sentry.client.config.ts. Tension: console.error = (...args: any[]) => {. Outcome: Sentry.captureException(new Error(args.join(" ")));.

MATCHESSolution

Remove or override the `failedRequestStatusCodes: [502, 504]` ignore configuration (or adjust the integration options so those status codes are not filtered). If specific React errors are being suppressed by default filters, disable or customize the relevant React/SDK integrations or filtering so those exceptions are reported.

MATCHESSolution

consider converting those exceptions to normal log messages — in the Shopware core code. Tension: to improve logging to reduce them a lot. Outcome: We are right now working on improving our exceptions.

MATCHESSolution

provide an option to exclude Exceptions that can be ignored safely — the mentioned Monitoring Extension. Tension: find a way to provide an option. Outcome: I've created an internal Issue.

MATCHESSolution

A workaround would be to create a wrapper function for logging — for logging which explicitly captures exceptions. Tension: you'll need to change logging everywhere in your project. Outcome: except Exception as e: sentry_sdk.capture_exception(e).

MATCHESSolution

Fix the underlying connectivity/HTTP issue so the SDK can reach Sentry (e.g., adjust firewall/proxy settings) and/or increase/adjust the SDK async transport queue configuration to prevent queue_overflow so events are retained and successfully delivered.

MATCHESSolution

can safely be ignored, or filtered — According to the comments there. Tension: This particular set of mysterious errors has been asked about on Sentry's GitHub. Outcome: can safely be ignored, or filtered.

MATCHESSolution

Capture the available error details (e.g., log/serialize the error object) and, for network/CORS context, use Sentry breadcrumb hooks such as `beforeBreadcrumb` to record whatever network information is exposed to the JS layer.

MATCHESSolution

The Python Sentry package will create an issue for logging.error() calls by default. — It is equivalent to this explicit configuration:. Tension: event_level=logging.ERROR # Send errors as events. Outcome: LoggingIntegration( level=logging.INFO, # Capture info and above as breadcrumbs event_level=logging.ERROR # Send errors as events ).

MATCHESSolution

when you capture exception, add transactionName to `scope`. Tension: you can also enhance event in `beforeSend` method. Outcome: scope.setTransactionName(`my custom title for error`);.

MATCHESSolution

Update Sentry initialization to include o.AddAspNet(); and in Application_Error call SentrySdk.CaptureException(Server.CaptureLastError());. For performance monitoring, also set TracesSampleRate and wrap request handling with Context.StartSentryTransaction() / Context.FinishSentryTransaction().

MATCHESSolution

If you want to filter all unhandled events on Flutter — Flutter. Outcome: you may be interested in this issue https://github.com/getsentry/sentry-dart/issues/456.

MATCHESSolution

you can specify the level of errors to be sent — In the Senter you can specify the level of errors to be sent. Tension: all errors are tracked successfully, but I still haven't found a way to identify if the error reported by Sentry is a common error or is crashing the app. Outcome: Please visit this url (diagnosticLevel).

MATCHESSolution

instead of relying on `CaptureConsole` — To capture the socket exceptions. Tension: Get all open websockets. Outcome: Once this is achieved and you have all sockets in play, tag on to the onclose and send it to sentry.

MATCHESSolution

Ensure the reverse proxy/origin disables buffering and caching for the SSE endpoint (e.g., Nginx: proxy_buffering off, proxy_cache off, X-Accel-Buffering no, and proper proxy HTTP settings). Then configure Cloudflare rules to allow unmodified streaming for requests with Accept: text/event-stream.

MATCHESSolution

You can modify the Exception Message by overriding `OnExceptionTypeFilter` in your AppHost — in your AppHost. Outcome: responseStatus.Message = Sanitize(responseStatus.Message);.

MATCHESSolution

Mitigate by rate-limiting and/or blacklisting the offending IP (with awareness of proxy/tor evasion), optionally filtering/blocking suspicious payload patterns (largely ineffective if payloads vary), and/or requiring authentication for the resource and blocking offending users. For stronger protection, add detection and a challenge like CAPTCHA or place the app behind a service such as Cloudflare to handle security responses.

MATCHESSolution

Might be worth just suppressing this CVE (or CPE) entirely — as I don't think that this project can be imported as an artifact. Outcome: just suppressing this CVE (or CPE) entirely.

MATCHESSolution

display error messages from API responses (both nested and non-nested). Tension: The alert system should be available globally across all components. Outcome: Alerts should be dynamically triggered based on different responses (error, success, etc.).

MATCHESSolution

track errors across the Flux — stopSignal = Sinks.one();. Tension: signal termination when the threshold is reached. Outcome: takeUntilOther(stopSignal.asMono()).

MATCHESSolution

To suppress this message, just turn off the corresponding log using `-Xlog` JVM option: — If, instead of disabling this log altogeter, you prefer to redirect it to `stderr`. Tension: This is creating parsing conflicts with any other user applications printing their output on stdout at same time.

MATCHESSolution

Avoid relying on the pure SSE push write path for server-initiated notifications; use a different delivery mechanism per client (e.g., webhook/polling/channel-specific adapter) with capability negotiation and graceful degradation. Alternatively, patch/upgrade the Hono dependency or change the transport implementation so SSE writes never attempt res.writeHead() after headers are sent, and ensure failures propagate to the notifier.

MATCHESSolution

Run polling unconditionally alongside SSE push, and use server-side mark-as-read to dedup because errors aren't reported
