shortestcovint() and .allpars fail for bootstrap results of zerocorr model

[HaiyangJin]

using MixedModels, Random # MixedModels version: v4.2.1

lmm = fit(LinearMixedModel,
	@formula(reaction ~ 1+days+(1+days|subj)),
	MixedModels.dataset("sleepstudy"))
bs = parametricbootstrap(MersenneTwister(42), 2000, lmm);
shortestcovint(bs)
bs.allpars

All the above codes work well.

lmm_zero = fit(LinearMixedModel,
	@formula(reaction ~ 1+days+zerocorr(1+days|subj)),
	MixedModels.dataset("sleepstudy"))
bs_zero = parametricbootstrap(MersenneTwister(42), 2000, lmm_zero);
shortestcovint(bs_zero)
bs_zero.allpars

However, shortestcovint() and .allpars fail when zerocorr model is used. The error messages are the same:
LoadError: type Diagonal has no field data.

Could you please help with this? Thanks in advance.

Should be fixed in the new release
