The marginal effect depends on all covariates including the random
effects. The random effects is the stochastic quantity that the
error message complaints about. I think that the easiest solution
is to report odds ratios. This has the added advantage that it
also makes the interpretation of the interaction effects much
easier.
Hope this helps,
