Additional Comments

Not sure if this is intended behaviour and I'm just passing the BigInts incorrectly or if it's an actual bug. If this is intended please show me how it should be done correctly

As a workaround I'm using .toString() on every bigint value before I'm passing them which seems to work.

I'm using Express with the pug view engine so I'm not sure if this is an Express error or pug. If it's Express I'll post it to their github instead
