Step 4: Get a dataset to add rows into a Power BI table ( Example: Push a dataset into a dashboard)

Hi,

I got as far as the last step in this example: adding rows to the dataset.

Greated the token, created the dataset en got back the datasetID.

When adding the rows I got the error-message in Visual Studio on the code-line 

var response = (HttpWebResponse)request.GetResponse();

:

"An unhandled exception of type 'System.Net.WebException' occurred in System.dll 

Additional information: De externe server heeft een fout geretourneerd: (404) Niet gevonden."

Can someone help me out on this ?
