TypeError on login

[Necroni]

Error produced on login. User does have an item in the wishlist that has price listed as a non-number - that's my first guess as to a solution. This means we'd want to sanitize data such that only numbers can be input in the wish form, maybe?

Error reads:

This error ONLY seems to exist if there is a wishlist item with a "price" attribute that is not a number. For example, if price: "$222" exists in a collection, this will break the login.

Since we've now added number validation to the input (and therefore can't be repeated without directly editing the database), this issue should take a back seat to other more pressing issues.

Possible future solution is to add a new ensureNumber function into the middleware, so that the client checks whether the input is a number before attempting to submit to the database.
