AmazonPollyClient and AmazonS3Client constructor throwing exception

[allmomoro088]

Describe the bug

Executing the following code throws an exception on var client = new AmazonPollyClient(credentials: c, region: RegionEndpoint.USEast1);, I also tested with S3 and the same error happened.

`var text = "Hi, I'm finally playing here.";

var c = new BasicAWSCredentials("AKEY", "ASECRET");

var s3 = new AmazonS3Client(c, RegionEndpoint.USEast1);

var client = new AmazonPollyClient(credentials: c, region: RegionEndpoint.USEast1);

var r = new SynthesizeSpeechRequest()
{
Engine = Engine.Neural,
OutputFormat = OutputFormat.Mp3,
SampleRate = "24000",
VoiceId = VoiceId.Joanna,
LanguageCode = LanguageCode.EnUS,
Text = text,
TextType = TextType.Text
};

var response = client.SynthesizeSpeechAsync(r);`

Expected Behavior

Go through the entire code and acquire the response of SynthesizedSpeech.

Current Behavior

Throwing exception on:
var client = new AmazonPollyClient(credentials: c, region: RegionEndpoint.USEast1);

Reproduction Steps

Just paste the code provided above, use the latest SDKs available on nuget (AWSSDK.Core 3.7.200.15, AWSSDK.Polly 3.7.202.7 and AWSSDK.S3 3.7.201.13) and run the code with actual credentials.

Possible Solution

No response

@allmomoro088 Thanks for opening the issue. Could you please share the exact error thrown? Also, could you please enable verbose logging using below code (works well when using console application) and share the detailed verbose logs:

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

I just tested below S3 code using latest version of AWSSDK.S3 and it works fine. So most likely it's the issue with your environment, may be credentials or IAM policy.

using (AmazonS3Client client = new AmazonS3Client(RegionEndpoint.USEast1))
{
    var listObjectsV2Response = await client.ListObjectsV2Async(new ListObjectsV2Request() { BucketName = "<<some-bucket>>" });
}

Thanks,
Ashish

Hi @ashishdhingra
Just ran the following code:

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

    var text = "Hi, I'm finally playing here.";

    var c = new BasicAWSCredentials("A", "B");

    var client = new AmazonPollyClient(credentials: c, region: RegionEndpoint.USEast1);

    var r = new SynthesizeSpeechRequest()
    {
        Engine = Engine.Neural,
        OutputFormat = OutputFormat.Mp3,
        SampleRate = "24000",
        VoiceId = VoiceId.Joanna,
        LanguageCode = LanguageCode.EnUS,
        Text = text,
        TextType = TextType.Text
    };

    var response = client.SynthesizeSpeechAsync(r);

    Console.WriteLine(response);
}
catch(Exception ex)
{
    Console.WriteLine(ex.Message);
    Console.WriteLine(ex.StackTrace);
    Console.WriteLine(ex.InnerException.Message);
    Console.WriteLine(ex.InnerException.StackTrace);
}
Console.Read();

@allmomoro088 Could you please check your shared credentials file, normally under %USERPROFILE%/.aws and if it contains a profile (may be default) with invalid or blank region? If yes, kindly set it to valid region or remove region key all together.

Thanks,
Ashish

@ashishdhingra ,
Thank you that worked, my credentials file had default profile without region defined. However that leads me to think, since I'll be shipping a game the possibility of creating a profile is remote and it will need access to services such as S3 and Polly, how can that be done?
Also, have that been a recent change? I ask that because I haven't changed anything in my development environment since my last development and and other softwares I developed has stopped working as well.

@allmomoro088 This has not been a recent change. May be you used AWS CLI aws configure without specifying region value and it created the profile with missing region value.

Since you might be distributing your game, you might use Cognito and configure role in Cognito for authenticated users. Please follow online articles for more guidance.
