I’m trying to follow along with Bayesian workflow for disease transmission modeling in Stan, but unfortunately I can’t get the example to run. I’ve used exactly the code provided in the tutorial with no alterations, but I get the error
 "Error in sampler$call_sampler(args_list[[i]]) : "  " c++ exception (unknown reason)" error occurred during calling the sampler; sampling not done
I found this, which seemed to suggest the error could be within the negative binomial function. But the suggested fix doesn’t appear to work for me. Any thoughts?
