Session Replays: dashboard is empty

[iramzyy]

Expected Behavior

I should see the recorded sessions on the dashboard

Current Behavior

The dashboard is empty and i'm getting this error in the Xcode consle:

Error: [StorageCoordinator] Failed to upload block file:///var/mobile/Containers/Data/Application/725D448F-E8AD-424C-AF73-416FEB9D40D5/Library/Application%20Support/com.amplitude.sessionreplay/f18ccdf553d28a4794706249bb383587/CA9152FD-6347-43BF-9976-5CB6C6F0BAAC_1727772540273_0.replay: Error Domain=NSCocoaErrorDomain Code=260 "The file “CA9152FD-6347-43BF-9976-5CB6C6F0BAAC_1727772540273_0.replay” couldn’t be opened because there is no such file."

Steps to Reproduce

My current Implementation is:

import AmplitudeSwift
import AmplitudeSwiftSessionReplayPlugin

    let amplitude = Amplitude(configuration: Configuration(apiKey: XXXX,
                                                           logLevel: .DEBUG,
                                                           autocapture: [.appLifecycles,
                                                                                           .sessions]))

   amplitude.add(plugin: AmplitudeSwiftSessionReplayPlugin(sampleRate: 1))

And i have enabled the session replay from the dashboard settings

Environment

I'm Using iOS SDK

• AmplitudeSessionReplay 0.0.2
• AmplitudeSwift 1.9.2
• AmplitudeSwiftSessionReplayPlugin (0.0.2)

Session is recorded only if it's the first launch after i open the app for the second time i'm getting this error and sessions is not recorded

Hi @iramzyy, please update to v0.0.8 if you haven't already.

[iramzyy]

Already updated and still the same problem @crleona

[crleona]

Hi @iramzyy, sorry for the delayed replay. We've fixed a few more setup issues in the latest version (0.0.12). If that still doesn't resolve the issue, could I ask you to share your full Amplitude setup code? (ie, are there any additional configurations around serverZone or serverURL)?

Hello, guys. The same issue:
Error: [StorageCoordinator] Unable to retrieve info for block file:///var/mobile/Containers/Data/Application/<ID>/Library/Application%20Support/com.amplitude.sessionreplay/<api_key>/_1737433081924_7.replay, removing

Setup Code from AppDelegate.swift:

import AmplitudeSwift
import AmplitudeSwiftSessionReplayPlugin
...

let amplitude = Amplitude(configuration: Configuration(apiKey: <api_key>))
amplitude.logger = CustomAmplitudeLogger()
         
let sessionReplayPlugin = AmplitudeSwiftSessionReplayPlugin(sampleRate: 1.0, enableRemoteConfig: false)
amplitude.add(plugin: sessionReplayPlugin)

Podfile:

...
target 'Runner' do
  use_frameworks!
  use_modular_headers!

  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
  pod 'AmplitudeSessionReplay', :git => 'https://github.com/amplitude/AmplitudeSessionReplay-iOS.git'
  pod 'AmplitudeSwiftSessionReplayPlugin', :git => 'https://github.com/amplitude/AmplitudeSessionReplay-iOS.git'

  target 'RunnerTests' do
    inherit! :search_paths
  end
end
...

I develop flutter iOS app and want to add this iOS-Native plugin to track session replay, but it only takes me empty 0sec records:

Flutter 3.27.1, XCode 16.2, iOS 18.2, AmplitudeSessionReplay-iOS Ver. 0.1.0

Hi @niktishakov, could you confirm the deviceId from the given Amplitude instance (either if you are setting it, or by querying amplitude.getDeviceId()). It looks like it may be an empty string here ("") which would cause issues.

[niktishakov]

Hi @crleona , I'm not sure in that, because later in AppDelegate I'm setting deviceId by Flutter's method channel (fyi, I also use amplitude_flutter dependency on Flutter's side):

let sessionReplayChannel = FlutterMethodChannel(name: "session_replay", binaryMessenger: controller.binaryMessenger)
        sessionReplayChannel.setMethodCallHandler({
            (call: FlutterMethodCall, result: @escaping FlutterResult) -> Void in
            if call.method == "init" {
                // Initialize the standalone session replay SDK
                print("[Amplitude] Initializing Amplitude")
                if let arguments = call.arguments as? [String: Any],
                   let deviceId = arguments["deviceId"] as? String,
                   let sessionId = arguments["sessionId"] as? Int64 {
                    
                    print("Device ID: \(deviceId)")
                    print("Session ID: \(sessionId)")
                    
                    amplitude.setDeviceId(deviceId: deviceId)

                    result(nil)
                } else {
                    result(FlutterError(code: "INVALID_ARGUMENTS", 
                                      message: "Missing or invalid deviceId/sessionId", 
                                      details: nil))
                }
            } else if call.method == "stopRecording" {
                print("[Amplitude] Removing Session Replay Plugin")

                print("[Amplitude] Session Replay Plugin removed")
                result(nil)
            }
        })

Here is non-empty deviceId that I successfully use with amplitude.setDeviceId.

In addition I can say, that every session in amplitude dashboard has non-empty deviceId in user props as shown on screenshot below:
