series is not periodic or has less than two periods (R in Tableau)

Question

I am doing time series decomposition of beersales data using the R language in Tableau. I am trying to decompose the Trend, but when I drag created Trend calculation field (see. attached) there is an always error:

An error occurred while communicating with data source 'Analytics Extension'

Error Code:6116DD27
An error occurred while communicating with the Analytics Extension.
An error occurred while communicating with the Analytics Extension.
Error in stl(tmp_table, s.window = "periodic", robust = TRUE) : 
  series is not periodic or has less than two periods

However, when I run this code in RStudio, it works:

tmp_table <- ts(beersales$Sales, frequency=12);
stl_data <- stl(tmp_table, s.window='periodic', robust=TRUE);
stl_data$time.series[,2]

I followed the instruction given here, but I am still struggling to solve this issue, but still, no solution on the horizon, does anybody have any idea where is the problem?
