Aws-sdk-net: S3 giving exception

[genifycom]

Trying to push a number of images to S3 from DotNet API and I am receiving an unhandled exception at random points (see below). This is not being trapped by try catch.

The requests look valid and it fails at different images in different runs.

This is from the AWSSDK api in DotNet Core 2.0 using

PutObjectResponse response = Task.Run(() => client.PutObjectAsync(putRequest)).Result;

1. Why is this not being trapped?
2. How can I debug this further?

Thanks

I think what you want is

PutObjectResponse response = client.PutObjectAsync(putRequest).Result;

[genifycom]

Good point, no need to double aync it. Thank you for that.

PutObjectResponse response = client.PutObjectAsync(putRequest).Result;

I made the change and ran again. This time it only gets to 1,180 objects before getting the following:

Seems like your code disposesAmazonS3Client and attempt to reuse it later. This does't look related to any issues in the SDK.

[genifycom]

It seems that moving the S3 client creation closer to the put call improves things

using (client = new AmazonS3Client(aws_access_key, aws_secret_key, Amazon.RegionEndpoint.USEast1))
{
PutObjectResponse response = client.PutObjectAsync(putRequest).Result;
}
