attempt to set an attribute on NULL

[simran-k]

Error in data.table::rbindlist(.data, ...) : 
  attempt to set an attribute on NULL

I am getting this error at:

FBInsightsExpanded <<- list.stack(list.select(FBInsightsExpanded, website_purchase_roas = website_purchase_roas$action_link_click_destination));
  print(FBInsightsExpanded)

This is what the DF looks like. I am guessing I need to replace NULLs with NA's. But not able to get a fix for it so far

Sorry to close the ticket, but this ticket/problem is not specific to the fbRads package, but you have a question related to data transformations that I cannot support. I'd suggest checking other functions of the rlist package, or even an rapply could do the trick.
