Fine-uploader Azure upload Url is being changed - azure

Question

I had my project working in Core 1, but when I changed to Core 2 it,no longer uploads the images to Azure.I get a 404 response code and "Problem sending file to Azure" message. The correct URL is returned from the server, but then,finuploader calls a URL with current URL in Front
The URL in chrome Console returning the 404 is shown as
https://localhost:44348/House/%22https://Customstorage.blob.core.windows.net/images/b0975cc7-fae5-4130-bced-c26272d0a21c.jpeg?sv=2017-04-17&sr=b&sig=UFUEsHT1GWI%2FfMd9cuHmJsl2j05W1Acux52UZ5IsXso%3D&se=2017-09-16T04%3A06%3A36Z&sp=rcwd%22
This is being added to the URL somewhere
https://localhost:44348/House/%22
I create the SAS with
public async Task<string> SAS(string bloburi, string name)
{
CloudStorageAccount storageAccount = new CloudStorageAccount(
new Microsoft.WindowsAzure.Storage.Auth.StorageCredentials(
"<storage-account-name>",
"<access-key>"), true)
CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
CloudBlobContainer container = blobClient.GetContainerReference("images");
return await Task.FromResult<string>(GetBlobSasUri(container, bloburi));
}
private static string GetBlobSasUri(CloudBlobContainer container, string blobName, string policyName = null)
{
string sasBlobToken;
// Get a reference to a blob within the container.
// Note that the blob may not exist yet, but a SAS can still be created for it.
var uri = new Uri(blobName);
//get the name of the file from the path
string filename = System.IO.Path.GetFileName(uri.LocalPath);
CloudBlockBlob blob = container.GetBlockBlobReference(filename);
if (policyName == null)
{
// Create a new access policy and define its constraints.
// Note that the SharedAccessBlobPolicy class is used both to define the parameters of an ad-hoc SAS, and
// to construct a shared access policy that is saved to the container's shared access policies.
SharedAccessBlobPolicy adHocSAS = new SharedAccessBlobPolicy()
{
// When the start time for the SAS is omitted, the start time is assumed to be the time when the storage service receives the request.
// Omitting the start time for a SAS that is effective immediately helps to avoid clock skew.
SharedAccessExpiryTime = DateTime.UtcNow.AddHours(1),
Permissions = SharedAccessBlobPermissions.Read | SharedAccessBlobPermissions.Write | SharedAccessBlobPermissions.Create | SharedAccessBlobPermissions.Delete
};
// Generate the shared access signature on the blob, setting the constraints directly on the signature.
sasBlobToken = blob.GetSharedAccessSignature(adHocSAS);
}
else
{
// Generate the shared access signature on the blob. In this case, all of the constraints for the
// shared access signature are specified on the container's stored access policy.
sasBlobToken = blob.GetSharedAccessSignature(null, policyName);
}
// Return the URI string for the container, including the SAS token.
return blob.Uri + sasBlobToken;
}
