Domain error when using optimize_prior!

[pasq-cat]

I was doing some tests for that paper i mentioned last time and sometimes when i try to fit the priors with

LaplaceRedux.fit!(la, data_loader)
optimize_prior!(la;verbose = false, n_steps = 200)

i get this error message

DomainError with -1.0:
log was called with a negative real argument but will only return a complex result if called with a complex argument. Try log(Complex(x)).
