Cannot access a closed stream when uploading to AWS S3










2














I'm trying to upload a file into AWS S3 from my .NET core application.



I create a PDF of type byte and I pass it to the following function:



public async Task<S3Response> UploadFileAsync(string bucketName, byte file)

try

var fileTransferUtility = new TransferUtility(_s3Client);
var fileTransferUtilityRequest = new TransferUtilityUploadRequest

BucketName = bucketName,
StorageClass = S3StorageClass.Standard,
PartSize = 6291456,
CannedACL = S3CannedACL.NoACL,
Key = "Test.pdf"
;

using (var ms = new MemoryStream(file))

fileTransferUtilityRequest.InputStream = ms;


await fileTransferUtility.UploadAsync(fileTransferUtilityRequest);

catch (AmazonS3Exception e)

return new S3Response

Message = e.Message,
Status = e.StatusCode
;




The error that my catch handler is triggering is:




Cannot access a closed stream




What am I doing wrong?
