App boot causes infinite stream of logs

[daankennes]

Summary

Upon booting the app, Sentry starts logging the almost exact same message ad infinitum. Moreover, I cannot seem to log any error to the platform. I do not receive an error message. If I log the same error twice, I do get a message saying the error will not be logged since it is a duplicate. However, nothing is registered on the online dashboard.

Configuration: `import * as Sentry from 'sentry-expo';

(sentry-expo is also included in the Expo config plugins array)

Manual error logging: `private static logToSentry(error: Error, info?: {componentStack: string}) { if (!(error instanceof NoInternetConnectionError) && !(error instanceof CanceledError)) { if (!DEV) { // I flipped this during testing console.log('logging to sentry'); Sentry.Native.captureException(error, this.getExtraInfo(info)); throw error; } else { console.debug('Sentry error logging disabled in development mode.'); } } }

private static getExtraInfo(info?: {componentStack: string}) {
    return {
        tags: {
            localTime: new Date().toString(),
            serverURL: store.getState().session.configuration?.server,

        },
    };
}`

Update: my dsn was wrong. Issues now get registered to the dashboard. However, the endless stream of log is not resolved and I would except an error when a wrong dsn is used.

I noticed I get an error 'App start was never finished' now.

[krystofwoldrich]

I believe there is a troubleshooting guide for this problem here https://docs.expo.dev/guides/using-sentry/#troubleshooting

[statico]

I am also seeing this.

Sentry.init({
  dsn: appConfig.config.sentryDsn,
  environment: appConfig.environment,
  enableInExpoDevelopment: true,
  sampleRate: 1.0, // Track all sessions for now
  tracesSampleRate: 1.0,
  debug: true,
})

results in

package.json:

〉grep sentry package.json
    "@sentry/react-native": "4.15.2",
    "sentry-expo": "~6.2.0",

Adding this to Sentry.init() seems to stop it from looping:

  integrations: [
    new Sentry.Native.ReactNativeTracing({
      enableAppStartTracking: false,
    }),
  ],

[statico]

Actually, this not only solves the looping, but without it Sentry doesn't send tracing at all:

const routingInstrumentation =
  new Sentry.Native.ReactNavigationV4Instrumentation()

Sentry.init({
  ...
  integrations: [
    new Sentry.Native.ReactNativeTracing({
      routingInstrumentation,
    }),
  ],
})

This is probably because we're still on Expo v48, not v49, and thus @sentry/react-native v4 instead of v5.

This error is caused by the HTTP request tracking, which creates spans for log requests (Starting 'http.client' span on transaction...) to the development server. To fix this, stop creating spans by adding the following code snippet:

import * as Sentry from 'sentry-expo'; import Constants from 'expo-constants';

Sentry.init({ tracesSampleRate: 1.0, integrations: [ new Sentry.Native.ReactNativeTracing({ shouldCreateSpanForRequest: url => { return !DEV || !url.startsWith(http://${Constants.expoConfig.hostUri}/logs); }, }), ], });

[weeksie]

I'm still getting this and the above solutions do not stop the infinite loop. I'm on Expo 49 but still on react-navigation

 LOG  Sentry Logger [log]: [Tracing] new activities count 0
...(forever)

I will note that this only happens on "cold start" after I've quit the simulator and restarted it.

Sentry.init({
    dsn: config.sentry.dsn,
    enableInExpoDevelopment: false,
    debug: true,
    tracesSampleRate: 1.0,
    integrations: [
        new Sentry.Native.ReactNativeTracing({
            shouldCreateSpanForRequest: (url) => {
                const shouldTrack = !isDev || !url.startsWith(`http://${Constants.expoConfig?.hostUri}/logs`);
                console.log({ shouldCreateSpanForRequest: shouldTrack });
                return shouldTrack;
            }
        })
    ]
});

That console.log never traces, so shouldCreateSpanForRequest seems like a red herring here.

/// edit:

When I call init on Sentry.Native (Sentry.Native.init({...) I get a trace, buuuuuuuuut I get an infinite stream of that trace even though shouldCreateSpanForRequest is returning false:

 LOG  {"shouldCreateSpanForRequest": false}
 LOG  {"shouldCreateSpanForRequest": false}
 LOG  {"shouldCreateSpanForRequest": false}
 LOG  {"shouldCreateSpanForRequest": false}
 LOG  {"shouldCreateSpanForRequest": false}
 LOG  {"shouldCreateSpanForRequest": false}
...

Hahaha, thanks for following me on this magical journey of discovery. I guess that method gets hit a lot. With enableAppStartTracking: false I am not getting the infinite loop anymore.

en fin, the solution for me was to follow the above instructions but to call Sentry.Native.init NOT Sentry.init

[appsgenie]

so what would be the best init option on expo Expo SDK 49? Should I use Sentry.Init() or Sentry.Native.init() ?
