Bayesian GLM in R using inverse gaussian family

Bayesian GLM in R using inverse gaussian family

I am trying to fit a bayesian glm model to my data assuming an inverse
family of distribution and link=(identity). I am getting the followiing
message:
Error in if (iter > 1 & abs(state$dev - devold)/(0.1 + abs(state$dev)) < :
missing value where TRUE/FALSE needed
I'm not quite sure why I'm getting an error msg as my code works for
family =gaussian and link=identity.
Any assistance would be appreciated.
