ggplot is giving error on Aesthetics, when ggplots are saved in list through loop for later use

error message:
"Aesthetics must be either length 1 or the same as the data (6): fill, width, x, y"

It is stopping to produce more ggplot graphs.
However, when it is run outside the loop, it is runnign very normally, without any such message.
problem arise in gps[[34]] dataframe.

When it was tructuanted to contain the same number of factor levels (2 b, 2g) in variable 1 (v1), no problem arised.
In dataframes 35 to 37 no problem arise!

 lst = list()
  for (i in 34:length(gps)) {
       
    p<-ggplot(data = gps, aes(x = gps[,3], y=gps[,1]) ) +
      geom_col( aes(fill = "", width=0.8 ))
    
    lst[[i]]<-p
  }

This doesn't work because you should never include the data in the aes(). I'd recommend asking for more help on the ggplot2 mailing list.

Thank you for your responce.
where can I find that mailing list?
