Cannot launch workers in R script

[#1]

I'm trying to spawn workers as part of my R script, however, I keep getting the following error. Any ideas on the root cause of this issue would be greatly appreciated.

library("cdsw")
workers <- launch.workers(n=2, cpu=0.2, memory=0.5, env="", code="print('Hello from a CDSW Worker')")
Error in curl::curl_fetch_memory(url, handle = handle) : 
  Timeout was reached: Connection timed out after 10001 milliseconds

Hi Ibi,

Are you hitting this on the 1.4.0 version? We are tracking a bug related to this (DSE-4293) and documented a workaround:

Correct, I'm using CDSW 1.4. The workaround has resolved the issue.

Thank you
