From @xni7 in #581 review. Chart export was not successful - server error. Seems to be caused by multi-domain charts: AE explorer and Tendril. Single domain charts seem to work.
Warning in if (chart$domain == "multiple") { :
the condition has length > 1 and only the first element will be used
aeExplorer has an init.
Quitting from lines 71-106 (report.Rmd)
Warning: Error in UseMethod: no applicable method for 'select' applied to an object of class "NULL"
