@A5hleyRich wanna take a look at this one?

[tillkruss]

@A5hleyRich It's add_multiple_at_once() and delete_multiple_at_once() being called. Can you try calling them with [null, false, 1, -10] and other terrible keys?

[A5hleyRich]

@tillkruss no dice. I've tried passing various data through add_multiple_at_once() and `delete_multiple_at_once() but I can't get this error to happen.

I think we can just switch the operator from ?? to ?: for all call pipeline calls:
