Python upload of local CSV file returns error - Error:500 Item does not have a file

Hi,

Help with the following issue (Error:500 Item does not have a file) would be greatly appreciated

I have written the following python script with the assistance of some sample code I found and with the aid of ArcGIS Online Rest help documentation. You will note I have used 2 alternative methods to upload the same locally stored CSV file onto my orginisation's ArcGIS Online site. Both methods return the status of "Success" specifically with a message such as "{"success" : true,"id" : "0ded368614754acd88d00084d5804a7d","folder" : null}"

The upload at first glance looks fine as on the ArcGIS Online site a new item appears added to 'My Contents' and is correctly named with properties correctly populated by the python code. However, when I try to open the CSV file ArcGIS Online returns the error - Error:500 'Item does not have a file'.

Can someone please take a look at the code and suggest what may be the cause of error? I tried to upload different files including some in KML file format and got the exact same error.

The code below has dummy user-name and password details added and currently assumes that the local file is stored "'E:\sample.csv"
