[Unity] [Android] I got Exception when sending data to Kinesis Stream on Android

[GearThuanDV]

Describe the bug

I am using AWSSDK in unity to send data from my game to Kinesis Stream. My credential is CognitoAWSCredentials

After I finish my implementation, I can send events to Kinesis Stream on Unity Editor. But on Android, it does not work.
I got this exception on Android:

System.AggregateException: One or more errors occurred. ---> System.Net.Http.HttpRequestException: An error occurred while sending the request ---> System.Net.WebException: Error getting response stream (ReadDone2): ReceiveFailure ---> System.Exception: at System.Net.WebConnection.HandleError (System.Net.WebExceptionStatus st, System.Exception e, System.String where) <0x00000 + 0xffffffff> 0 in <00000000000000000000000000000000>:0 at System.AsyncCallback.Invoke (System.IAsyncResult ar) <0x00000 + 0xffffffff> 0 in <00000000000000000000000000000000>:0 at System.Action.Invoke () <0x00000 + 0xffffffff> 0 in <00000000000000000000000000000000>:0 at System.Threading.ContextCallback.Invoke (System.Object state) <0x00000 + 0xffffffff> 0 in <00000000000000000000000000000000>:0 at System.Threading.ExecutionContext.RunInternal (System.Threading.ExecutionContext executionContext, System.Threading.ContextCallback callback,

Please help me to check this bug

Expected Behavior

Android can send events normally without exception

Current Behavior

The exception is thrown on Android devices when sending data to the Kinesis Stream

Reproduction Steps

• Create a unity 2019.4.38 empty project.
• Config project to run with: .Net Standard 2.0 and IL2CPP
• Integrating AWS SDK with Unity: AWSSDK.CognitoIdentity, AWSSDK.Core, AWSSDK.Kinesis, AWSSDK.SecurityToken, AWSSDK.KinesisFirehose
• Update link.xml
• Sent event to Kinesis Stream by using: CognitoAWSCredentials
• Build an Android project and check to send event functions on android devices.

Possible Solution

Hi @GearThuanDV,

Good morning.

Thanks for reporting the issue. Could you please the following:

• Exact NuGet version of AWSSDK.* packages used.
• Enable verbose logging using the code below and share the detailed logs:

Amazon.AWSConfigs.LoggingConfig.LogResponses = Amazon.ResponseLoggingOption.Always;
Amazon.AWSConfigs.LoggingConfig.LogTo = Amazon.LoggingOptions.Console;
Amazon.AWSConfigs.AddTraceListener("Amazon", new System.Diagnostics.ConsoleTraceListener());

• Share the minimal code snippet that is throwing error.

Thanks,
Ashish

Thank you for your reply @ashishdhingra,
I added this code:

Amazon.AWSConfigs.LoggingConfig.LogResponses = Amazon.ResponseLoggingOption.Always;
Amazon.AWSConfigs.LoggingConfig.LogTo = Amazon.LoggingOptions.SystemDiagnostics;
Amazon.AWSConfigs.AddTraceListener("Amazon", new System.Diagnostics.ConsoleTraceListener());

but Amazon.AWSConfigs.AddTraceListener("Amazon", new System.Diagnostics.ConsoleTraceListener()); does not work on unity

After updating the AWSConfigs, this is the new exception message on Android:

 System.AggregateException: One or more errors occurred. (The server returned an invalid or unrecognized response.) ---> System.IO.IOException: The server returned an invalid or unrecognized response.

This bug also happens with the latest version on NuGet:

• awssdk.cognitoidentity.3.7.100.36
• awssdk.kinesisfirehose.3.7.101.11
• awssdk.securitytoken.3.7.100.36
• awssdk.core.3.7.102.4
• awssdk.kinesis.3.7.100.36
  I copy dll of .net standard 2.0 to my unity project.

my code snippet:

 void OnSendSingleRecord() {
        logText.text = "sendingSingle";
        using (var memoryStream = new MemoryStream())
        using (var streamWriter = new StreamWriter(memoryStream))
        {
            streamWriter.Write(message_to_send1);
            var task = awsClient.PutRecordAsync(new PutRecordRequest
                {
                    Data = memoryStream,
                    PartitionKey = kinesis_stream_partition_key,
                    StreamName = delivery_stream_name
                }
            );
            
            task.ContinueWith(
                _ => {
                    if (_.Exception == null) {
                        Debug.LogError("===Single Success");
                        logText.text = "===Single Success";
                    } else {
                        Debug.LogError($"===Single Failed \n {_.Exception}");
                        logText.text = $"===Single Failed \n {_.Exception}";
                    }
                });
        }
    }
