Watson Studio Local Token Env Not Found in R script web service deployment

Troubleshooting


Problem

You are trying to deploy R script as web service in WML, in that script you have function with calling of data source that uses dsxCoreUtilsR library. You are getting Token Not Found error in the deployment pod log.

R script:
finstatadhoc <- function(args) {
  library(dsxCoreUtilsR)
  library(RJDBC)
  
  data_source_FS <<- getDataSourceInfo('db2wh')
  
  return(data_source_FS$user)
}

Cause

Since the DSX_token isn't exposed in to Renviron during R script web service deployment setup, you are getting the error. It is required for accessing remote dataset.

Environment

Watson Studio Local (1.2.3.1 with Patch 11)

Resolving The Problem

This issue is fixed in WSL (1.2.3.3) patch 02 , here is the workaround

  1. Via cluster console, add  
    echo "DSX_TOKEN='${DSX_TOKEN}'" >> /usr/lib/R/etc/Renviron in /user-home/.scripts/system/spawner/deployments/startup-r-server.sh
     after line 74. (Note: Use  
    echo "DSX_TOKEN='${DSX_TOKEN}'" >> $R_HOME/etc/Renviron
     for WSL (1.2.3.3) or newer.
  2. In WSL via browser, disable & enable the web service.
