The same started happening to us, already around 10k alerts on Sentry
It started happening to us almost 2 weeks ago after upgrading RN to 0.69.5 on logEvent call
appsflyer version is 6.4.40

[amit-kremer93]

@professorkolik @markushogberg this issue is related to internet connection. Do you see this only on logEvent call? what about initSdk?

[markushogberg]

@amit-kremer93 Looks like all (or at least most of) the errors happens on the logEvent call.

[professorkolik]

@amit-kremer93 seems to be gone on v6.9.1, still analyzing

[qasimgit]

same error on IOS, when calling logevent V6.9.2 RN version 0.67.3
Error: com.appsflyer.sdk.network

@GM-appsflyer

[qasimgit]

fixed this issue by adding the correct devKey and appId on the init of sdk.

appsFlyer.initSdk(
  {
    devKey: 'correct-dev-key',             ----> here
    isDebug: false,
    appId: 'your-app-id',                       ----> here
    onInstallConversionDataListener: true, //Optional
    onDeepLinkListener: true, //Optional
    timeToWaitForATTUserAuthorization: 10, //for iOS 14.5
  },
  (result) => {
    console.log('result from appsflyer initialization', result);
  },
  (error) => {
    console.error('error in appsflyer initialization', error);
  },
);

[amit-kremer93]

@markushogberg @professorkolik please confirm that you initialized the sdk properly before sending an event

[markushogberg]

@amit-kremer93 When I try it myself locally I can confirm that it is initialized with the correct values before sending any events.

[professorkolik]

@amit-kremer93 sdk was initialized properly, only thing that helped is to update to v6.9.1 from v6.4.40

[markushogberg]

We are currently on v6.8.2. In the next release of our app we will have v6.9.2. I'll keep you posted if that makes the issue go away.

[smn-snkl]

We are seeing this as well on v6.9.4 a lot recently. Any ideas why?

[markushogberg]

We are also still seeing these errors in v6.9.4.

[bishalfan]

We are also facing this issue after upgrading RN to 0.71

[dnvarun]

Any update here? We are also seeing this a lot

[amit-kremer93]

This issue can be related to a specific device or network and not to the sdk. I recommend you to contact our support team at support@appsflyer.com with all the relevant information so they can help you
