Often when using GSC connector i got this exception. I use default formula like this:
=Dump(Connector("GoogleSearchConsole.SearchAnalytics";"https://www.DOMAIN.pl/";"2016-12-01";"2017-02-13";"query=~"&A1;"web";"3";"0";"Page";FAŁSZ);PRAWDA)
I spread this formula for hundreds cells.
GSC api had some session time or it's a bug?
Edit:
When recalculate cells its working.
When this exception shows all remaining formula got this error.. (So for each remaining cell this message are show).
