R ggplot boxplot issues

I was currently attempting to create a boxplot for my RShiny application. I have some movies from a .csv. These movies are of various genres, and I would like to display them in boxplots per genre, but I cannot seem to get it to work.

The 'boxplots' currently look like this:
enter image description here

The code I used:

output$boxplot <- renderPlot({
p <- ggplot(all_movies, aes(x = Genre, y = Rating)) +
geom_boxplot()
p
})


How do I get proper boxplots for this dataset? All help is appreciated

EDIT
dput(all_movies)

Answer

Posting solution as an answer:

From your dput output we see that the Rating column is a factor, in order to pass it to ggplot like you want it to be it needs to be a numeric so we need to recode it as:

all_movies$Rating <- sapply(sapply(all_movies$Rating, as.character), as.numeric)

Then we can pass it to ggplot:

ggplot(all_movies) + geom_boxplot(aes(x = Genre, y = Rating))
