DataSource.Error: ADO.NET: R script error. HTTPS code: 401

[FaCoffee]

I was following this tutorial about how to use a pre-published Machine Learning Studio web service to score a bunch of rows in Power BI.

I am using an R script with the correct workspace id (wsid) and authentication code (authorization token) of my Machine Learning Studio web service. 

The R script is the following:

wsid = "<mywsid>"
 
auth = "<myauthtoken>"
          
serviceName = "<myservicename>"
 
library("AzureML")
 
ws <- workspace(wsid,auth)
ds <- consume(services(ws, name = serviceName),dataset)
ds<-data.frame(ds,dataset)
#output<-data.frame(ds$Sentiment,ds$Score)

However, when I run my R script I get the following error:

DataSource.Error: ADO.NET: R script error.
Error: AzureML returns error code:
HTTP status code : 401



Execution halted

Details:
    DataSourceKind=R
    DataSourcePath=R
    Message=R script error.
Error: AzureML returns error code:
HTTP status code : 401



Execution halted

    ErrorCode=-2147467259
    ExceptionType=Microsoft.PowerBI.Scripting.R.Exceptions.RScriptRuntimeException

What am I doing wrong? I feel like this might be an authentication problem (code 401), but in the tutorial I mentioned, this does not happen.

Hi @FaCoffee , 

Please checkwhether you install the AzureML package in your local R (or server) using install.packages command, and you also need to checkwhether your workspace , service name and authenticaltion token are correct.

Hi all, I checked these and they are all correct, but the error still remains.
