ggtern error - Error in f(..., self = self) : unused argument (plot$coordinates)

Question

Why I am getting this error? I have even tried a simple mock example below but still getting the error. Link for the mock example - Making a ternary plot

x  <- data.frame(
  x1 = c( 0, 0, 1, 0.1, 0.6, 0.2 ),
  x2 = c( 0, 1, 0, 0.3, 0.2, 0.8 ),
  x3 = c( 1, 0, 0, 0.6, 0.2, 0.0 )
)

library(ggtern)
ggtern(data=x,aes(x1,x2,x3)) + 
  geom_point(fill="red",shape=21,size=4)

Getting the following error:

Error in f(..., self = self) : unused argument (plot$coordinates)

Can anybody help me please?
