Tooltips in Custom R visual

I have followed the git tutorial to create an html custom visual with R. The visual is currently working if I add up to one tooltip column but crashes if I try to add more with the error:

"Aesthetics must be either lenght 1 or same as the data (754): x,y,colour,label"

I know it's possible to add more than one label to ggplot and this show correctly when using plotly specifying them as "label=c("label1","label2"...) so I am thinking that the problem has to do on how I am processing it on my script. The only line where I address tooltips is:

"geom_point(data = locations, mapping = aes(x = longitude, y = latitude, color = count, label= name)"

Any help will be really appreciated, thanks in advance!
