Error in cbind(yX1[[i]], V1) : number of rows of matrices must match (see arg 2) in r

I estimated a gmm model using pgmm() of the plm package, but received the following error term:

Error in cbind(yX1[[i]], V1) : number of rows of matrices must match (see arg 2)

My Model looks like this:

pgmm(X1 ~ X2 +X3 +X4 +X5| X6 +X7 +X8 +X9 +X10 +X11 +X12, data= mydata,                           
 effect = "twoways", model = "twosteps", transformation = "ld")

The Data and my R Script can be found here:
