Hello, thanks much for your interest in the Survey Solutions R API package. Package author here. I have seen your question just now.
Regarding your initial question: Yes, the package should run with any server running a recent version of Survey Solutions, under any domain.
As Sergiy already pointed out, the error seems to be thrown by the package, because of a lack of the questName variable. May i ask which server version you are using?
We had recently conducted an upgrade of the API, which is not yet reflected in the package. If you are using a very recent version, then this might be the reason.
I also see, that you are running:
questlist <- suso_getQuestDetails()
Did this work? Because if yes, then it is clearly the new API Syntax, which currently primarily affects the export.
In any case, i will update the package during the next days, and let you know. Simultaneously i will also check your specific error.
One more thing: Are you using the command inside a shiny application? I have seen, that your inshinyApp=T.
If you set this outside a shiny environment, it would also throw you an error, immediately after the above one.
