I can publish it, but the app cannot show the graphs.
I check the log and it says, Warning: Error in : Aesthetics must be either length 1 or the same as the data (1): x, y, label, vjust, fill
Also, there is another warning, Warning in Ops.factor(Year, start) : ‘>=’ not meaningful for factors.
It is pretty strange, because when I run the app on my own laptop, it works super well.
