Using the R script in PowerBI to connect to spotify via Rspotify Package - issue with OAuth

[Polly]

Hey,

I wonder if anyone can help

I am trying to run a function which leverages the RSpotify package. It works with no problems within R studio, however, it seems to have issue authorising when I try to run it in the PowerBI R scripter. I wonder if anyone has had a similar issue or has any suggestions?

Error Message: R script error. Error in httpuv::startServer(use$host, use$port, list(call = listen)) : Failed to create server Calls: Check_Genre ... init_oauth2.0 -> oauth_authorize -> oauth_listener -> Execution halted

My Function

ArtistName <- dataset$ArtistName[1] library(devtools) library(Rspotify)

Check_Genre <- function(ArtistName) {

   ClientID <- "********************"    Client_Secret <- "********************"
    keys <- spotifyOAuth("RSpotify_Project", ClientID, Client_Secret) 



   ArtistName <- as.vector(ArtistName)   artist_info <-  length(ArtistName)



   for(i in 1:length(ArtistName)){    ifelse(length(searchArtist(ArtistName[i], token = keys))>=1,       
           artist_info[i] <- searchArtist(ArtistName[i], token = 
                keys)$genres[1],                   artist_info[i] <- "")

  }   artist_info
     }      Genre <- Check_Genre(ArtistName)      library(wordcloud)       library(tm)     wordcloud(Genre, random.order = FALSE)

Thanks,

Polly

Hi Polly,

According to my test, the OAuth2 seems needing user interaction. However, Power BI Desktop will halt the R scripts if interactive calls happen. Please refer to desktop-r-scripts#prepare-an-r-script.

>>>Interactive calls in the R script, such as waiting for user input, halts the script’s execution

I wonder if this post could help.

Hey Dale,

Ah that's what I feared!

Thanks for your response I'll read the post post and see if I can get it to work

Thanks,

Hey,

and you should also be aware, that the Power BI Service does not allow to reach out to "foreign" web ressources. So, whatever you do with the Spotify data, the data has to be gathered locally and then published to the Power BI service manually.

There will be no way to configure an automatic refresh that allows running an RScript sourcing  a "foreign" web ressource.
