Invalid stanfit object produced from stan_betareg... stan_glm worked fine?

[SiegleJ798]

Summary:

I cannot run stan_betareg. Checked that all y variables are in hte proper support and updated the package. Still doesnt work

Description:

Running :
model<-stan_betareg(
linformula,
link=c('logit'),
data=train ,
model = TRUE,
x = TRUE,
y = TRUE,
contrasts = NULL,
weights = Insured.Acres,
QR=TRUE,
refresh=0,
prior= normal(0,2),
prior_intercept = normal(0,2)
)

[linformula is defined using as.formula to be:
PercentLoss ~ LossRatio.11 + ZeroIndemnities.11 + LossRatio.15 +
ZeroIndemnities.15 + LossRatio.16 + ZeroIndemnities.16 +
LossRatio.41 + ZeroIndemnities.41 + LossRatio.51 + ZeroIndemnities.51 +
LossRatio.78 + ZeroIndemnities.78 + LossRatio.81 + ZeroIndemnities.81 +
LossRatio.91 + ZeroIndemnities.91 + prec + dday0C + dday10C +
dday30C + prec2 + weightCovLevel.84 + totalpolicies | totalpolicies +
weightCovLevel.84 ]

gets the error:

[1] "Error in sampler$call_sampler(args_list[[i]]) : Initialization failed."
[1] "error occurred during calling the sampler; sampling not done"
