@5d : Can you tell me in your SDK when does error 7 is reported, it will help me replicate it. We are seeing lot of random failures, I will switch on the log and try to provide you soon. Also error clearly indicates this should not be happening.

[5d]

The error code 7 corresponds to StorageError.unknown. Several conditions can lead to StorageError.unknown error. To proceed with further investigation, we need at least the stack trace, logs, or steps to reproduce the issue.

Is there a way to dump AWS logs into local file , we dont have cloudwatch, Testers are able to reproduce it and will be easy if thats possible.

[5d]

You can enable verbose logging to the console by doing this before calling Amplify.configure:

Amplify.Logging.logLevel = .verbose

[Ankish]

@5d : Yes we can switch on the logs and watch console but we cant dump to a local file. Is there a way to do that ? We need to uploads tons of videos to replicate that. What would be the best way to pass the. logs to you ?

[5d]

Sorry, the default logging plugin utilizes os_log internally and it does not have an option to redirect the output stream to a file.

[Ankish]

@5d : Isnt there a way to make All AWS logging to be logged in AWS Cloud watch with this configuration:

 let loggingConstraints = LoggingConstraints(defaultLogLevel: .verbose)
        let loggingConfiguration = AWSCloudWatchLoggingPluginConfiguration(logGroupName: "/ios-development-analytics", region: "us-west-2", localStoreMaxSizeInMB: 1, flushIntervalInSeconds: 60, loggingConstraints: loggingConstraints)
        let loggingPlugin = AWSCloudWatchLoggingPlugin(loggingPluginConfiguration: loggingConfiguration)
        loggingPlugin.enable()
        try Amplify.add(plugin: loggingPlugin)```

[5d]

Yes. To access the logs remotely, you can utilize our Cloudwatch logging plugin. Please refer to our Cloudwatch logging setup documentation, which provides detailed instructions. In addition to the code snippet mentioned, there are other configurations required. For instance, you will need to attach the appropriate Cloudwatch permissions to your IAM roles.

Hi @Ankish , Based on the error in the log, it appears that your device's time is not synchronized with the world clock. Does your testing device have automatic time correction enabled? Please refer to the Apple documentation to set the time to automatic and verify if the issue persists.
