Error in prior_Pi_Sigma(lambda1 = x$lambda1, lambda2 = x$lambda3, prior_Pi_AR1 = x$prior_Pi_AR1, : Too low order

I am new using this package and I get this error, and I do not know what is for.

I am trying to forecast GDP with 3 monthly variables

`mf_dff=window(mf_df,start=c(2000,3),frequency=12) #las variables trimestrales no pueden empezar con NA

prior <- set_prior(Y = mf_dff, freq = c("m","m","q"),agreggation='triangular',
prior_Pi_AR1=2,
n_lags = 5, n_burnin = 5000, n_reps = 5000)

mod_ss_iw <- estimate_mfbvar(prior, prior = "minn")`
