Jomo not running imputation

Hi,

I am trying to run jomo imputation for the first time. My syntax seems to run well, at least no error messages are displayed. Yet, no imputation occurs when I run my syntax.

Here is my syntax:
class(Input_data$Dass2)
Y <- Input_data[, c("Dass2")]
Input_data$cons <- 1
X <- Input_data[, c( "LnBes1", "Dass1", "FFMwo1")]
imp = Input_data
set.seed(1569)
imp <- jomo(Y = Y, X = X, nburn = 1000, nbetween = 1000, nimp = 100)

Here is the message that come up after I run the above syntax :No clustering, using functions for single level imputation.

Thank you for your help.
