Error thrown by getUserFarmPosition in 1.2.23

[aantia]

I just updated the sdk to 1.2.23, and I'm now seeing an error when I call FranciumSDK.getUserFarmPosition(Web3.PublicKey). The error is UnhandledPromiseRejectionWarning: Error: Number can only safely store up to 53 bits. which I've seen when trying to convert overly-large BNs to Numbers, but it's being thrown before I actually touch any of the data. Here's the full trace:
