Amazon Interactive Video Service (IVS): GetStream and ListStreams unable to parse ISO-8601 formatted `startTime`

Describe the bug

Amazon Interactive Video Service (IVS) GetStream API and ListStreams API throw SdkClientException: Unable to parse date

The document describes startTime is ISO-8601 formatted timestamp.

Via the CLI, GetStream API returns the following response where startTime is actually in ISO-8601 format.

{
    "stream": {
        "channelArn": "arn:aws:ivs:...",
        "playbackUrl": "https://....m3u8",
        "startTime": "2020-11-24T18:06:27+00:00",
        "state": "LIVE",
        "health": "HEALTHY",
        "viewerCount": 0
    }
}

I implemented the following simple code using this SDK.

dependencies {
    implementation platform('software.amazon.awssdk:bom:2.15.34')
    implementation 'software.amazon.awssdk:ivs'
    ...
}

import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.ivs.IvsClient;
import software.amazon.awssdk.services.ivs.model.GetStreamRequest;

public class Main {
    public static void main(String[] args) {
        var region = Region.of(args[0]);
        var channelArn = args[1];

        var ivsClient = IvsClient.builder().region(region).build();
        var req = GetStreamRequest.builder().channelArn(channelArn).build();
        var res = ivsClient.getStream(req);

        System.out.println(res);
    }
}

I try to get the stream of the live channel with the above code. But it throws the following exception.

ListStreams API also throws a similar exception.

Steps to Reproduce

1. create a channel in IVS
2. start video streaming to the channel using like OBS
3. make sure you can watch the live streaming on the AWS Console
4. confirm the GetStream API and ListStreams API successfully return values via CLI
5. call GetStream API and ListStream API via SDK and it throws exception.

Yes! They are working on it, it’s not a simple task it seems.
