Exception on the file uploading with a x509 certificate device

[walkerlin-msft]

I got an exception on UploadFileToBlob method in the x509 certificate device.
Does it support file upload feature in the x509 device?

(Microsoft.Azure.Devices.Client) Version: 1.2.3

Here is the log:

Thanks for the help.

@walkerlin-msft - We had not enabled X509 with FileUpload yet. It is in our backlog to enable it. We also welcome contributions to our repo if this interests you. You can find our contribution guideline here: https://github.com/Azure/azure-iot-sdk-csharp/blob/master/CONTRIBUTING.md

Got it and will keep tracking the updates.
Thanks a lot.

Hello @walkerlin-msft have a look at the commit Issue #60: enabling X509 support with FileUpload and test it. The changes will be added to the master branch soon. Thanks :)!

All Best.

Hi @sergaz-msft thanks for your updates. I've tested it successfully in my codes. I'm look forward to see the release update in the master branch.
Thanks a lot.

I am trying to upload a file to IoT hub using x.509 certs but am receiving an exception every time. The exception is "Object reference not set to the instance of an object". The inner exception is below:

StackTrace [string]:" at Microsoft.Azure.Devices.Client.IotHubConnectionString.Microsoft.Azure.Devices.Client.IAuthorizationProvider.GetPasswordAsync()\r\n at Microsoft.Azure.Devices.Client.Transport.HttpClientHelper.ExecuteAsync(HttpMethod httpMethod, Uri requestUri, Func3 modifyRequestMessageAsync, Func2 isSuccessful, Func3 processResponseMessageAsync, IDictionary2 errorMappingOverrides, CancellationToken cancellationToken)\r\n at Microsoft.Azure.Devices.Client.Transport.HttpClientHelper.PostAsync[T1,T2](Uri requestUri, T1 entity, IDictionary2 errorMappingOverrides, IDictionary2 customHeaders, CancellationToken cancellationToken)\r\n at Microsoft.Azure.Devices.Client.Transport.HttpTransportHandler.UploadToBlobAsync(String blobName, Stream source)"

I am using Microsoft.Azure.Devices.Client 1.7.2. Is file uploading using x.509 still not supported?
