So this is the line that is triggering the error. It appears to be having a problem with that instance of `mongoose`.

There is a whole thread about transactions using Fawn (which has not been updated in years) and some code for changing this to just skip Fawn entirely (preferring to use mongoose transactions directly): [[Mongoose] Transactions vs Fawn (Two Phase Commits)](https://forum.codewithmosh.com/t/mongoose-transactions-vs-fawn-two-phase-commits/3281)

I think that the basic issue here is just that Fawn does not know how to recognize the current instance of mongoose since it has not been updated in so long.
