Not meaningful for factorsError in glmmLasso

Question

I am experiencing this error not meaningful for factorsError in if (xi > xj) 1L else -1L : missing value where TRUE/FALSE needed when trying to fit a lasso mixed model based on the R package glmmLasso and I can't quite figure out what's causing this.

My mdoel looks lik this

lassomodel<- glmmLasso(euclideaneye_mid ~ var1_z + var2_z + var3_z + var4_Z + 
                                 var5_z + var6_z + var7_z, 
                               rnd = list(Participant_ID =~1, Stimulus_ID=~1),
                               lambda=10, 
                               data = db1, final.re=TRUE)

Unfortunately, the cran documentation doesn’t clarify what's going on and there doesn’t seem to be a GitHub page to post any issues for this package.
