I have Azure IoT Hub Python. Trying to upload the files through this routine

def iothub_file_upload_sample_run():

try:

    print ( "IoT Hub file upload sample, press Ctrl-C to exit" )

    client = IoTHubClient(CONNECTION_STRING, PROTOCOL)      



    f = open(PATHTOFILE, "r")

    content = f.read()



    client.upload_blob_async(FILENAME, content, len(content), blob_upload_conf_callback)



    print ( "" )

    print ( "File upload initiated..." )

This works fine but the files content types are "application/octet-stream"

I went to some posts and tried by adding "client.set_options('auto_url_encode_decode', True)" as below

def iothub_file_upload_sample_run():

try:

    print ( "IoT Hub file upload sample, press Ctrl-C to exit" )



    client = IoTHubClient(CONNECTION_STRING, PROTOCOL)

    client.set_options('auto_url_encode_decode', True)



    f = open(PATHTOFILE, "r")

    content = f.read()



    client.upload_blob_async(FILENAME, content, len(content), blob_upload_conf_callback)



    print ( "" )

    print ( "File upload initiated..." )





But the response message is 

File:C:Releaseiot-sdks- 

internalsreleasepythonautomationaziotsdk_pytoolssrccc- 

utilityadaptershttpapi_winhttp.c Func:HTTPAPI_CloneOption Line:1046 

unknown option auto_url_encode_decode

unknown option auto_url_encode_decode and Protocol is HTTP

Not sure if this is limitation of Azure IoT Hub Python to default send Application/octet-stream

Any pointers would be appreciated
