Error "An item with the same key has already been added."

[VitaliBalyk]

Project on Xamarin Forms. Everything works on Android. But there is an error on iOS.
All packages have been updated to the latest version.
When I send a file to the bucket, I get an error "An item with the same key has already been added. Key: X-Content-Type-Options".
The file is definitely not in the bucket bin before the method is called. After the error, the file is in the bucket.

                var putObjectArgs = new PutObjectArgs()
                    .WithBucket(bucketName)
                    .WithObject(location + objectName)
                    .WithFileName(filePath)
                    .WithContentType(photo.File.ContentType);
                try
                {
                    await minio.PutObjectAsync(putObjectArgs).ConfigureAwait(false);
                }
                catch (Exception ex)
                {
                    Console.WriteLine($"PutObjectAsync exception: {ex.Message}");
                    throw ex;
                }
