Troubleshooting

Enable Debug Mode

You can enable the SDK's debug functionality through the following configuration. Once enabled, on Android, you can directly see the output debug logs in the Flutter compilation tool. For iOS, you'll need to compile and run using Xcode. You can also check the logs by using the macOS 'Console' application.

FTMobileFlutter.sdkConfig(
      serverUrl: serverUrl,
      debug: true, // enable debug mode
    );

It is recommended to disable this configuration when releasing the version.

Running Normally But No Data

  • Ensure Datakit is running properly.

  • Confirm that the SDK's upload address serverUrl is configured correctly and initialized properly. In debug mode, you can use the following logs to identify issues with the upload address configuration.

    // Check datakit address
    11:15:38.137 [FT-SDK]FTHttpConfigManager com.demo D serverUrl:http://10.0.0.1:9529

    // Network connect error log

    // Sync data success

// Before version 1.3.10, it won't print "Upload Response statusCode : 200". You can check the console for error logs. If there are no error logs, it indicates a successful upload.

  • Check if Datakit is uploading data to the corresponding workspace and whether it's in an offline state. You can confirm this by logging into Observability Cloud and checking the "Infrastructure" section.

pod install error

[!] CocoaPods could not find compatible versions for pod "FTMobileSDK/FTMobileAgent":
  In snapshot (Podfile.lock):
    FTMobileSDK/FTMobileAgent (= 1.3.9-alpha.14)

  In Podfile:
    ft_mobile_agent_flutter (from `.symlinks/plugins/ft_mobile_agent_flutter/ios`) was resolved to 0.0.2, which depends on
      FTMobileSDK/FTMobileAgent (= 1.3.10-beta.2)


You have either:
 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
 * changed the constraints of dependency `FTMobileSDK/FTMobileAgent` inside your development pod `ft_mobile_agent_flutter`.
   You should run `pod update FTMobileSDK/FTMobileAgent` to apply changes you've made.

If you encounter version import issues while compiling an iOS app, you need to run the following command in the terminal within your Flutter project's ios directory:

pod install --repo-update

Data Loss

Partial Data Loss

  • If you're missing certain Session data in RUM or logs in Trace, first make sure that you haven't set sampleRate < 1 in FTRUMConfig, FTLoggerConfig, or FTTraceConfig.
  • If you're not capturing all RUM data, such as missing Resource or Action data:

Resource and Action data are bound to Views. Ensure that you're using the startView operation. You can refer to the RUM-View documentation for implementing View event capturing.

  • Investigate network issues on devices uploading data and on devices running Datakit.
