object is not iterable (cannot read property Symbol(Symbol.iterator))

u.searchParams & h.searchParams may be null and causes a TypeError -- and noisy error in Sentry

File: commerce-sdk-isomorphic/lib/index.esm.js

Source functions: loginGuestUser: function (e, t) {return vI.apply(this, arguments);}, loginRegisteredUserB2C: function (e, t, r) {return mI.apply(this, arguments);},

Line with error: if (((d = e.sent), (c = (null === (i = d.headers) || void 0 === i ? void 0 : i.get("location")) || d.url), (u = new URL(c)), (l = Object.fromEntries(u.searchParams.entries())), !(d.status >= 400 || l.error))) {

Suggested change: u.searchParams.entries to u.searchParams?.entries ?? {} and same for h.searchParams

Hey @janderson-watchbox, thanks for creating this issue. Wanted to check something, have you confirmed that u.searchParams.entries() is null or is it an object? Asking as I tested passing around different inputs to Object.fromEntries() and this is what I found:

Object.fromEntries(undefined)

VM418:1 Uncaught TypeError: undefined is not iterable
    at Function.fromEntries (<anonymous>)
    at <anonymous>:1:8

Object.fromEntries(null)

VM433:1 Uncaught TypeError: undefined is not iterable
    at Function.fromEntries (<anonymous>)
    at <anonymous>:1:8

Object.fromEntries({})

VM448:1 Uncaught TypeError: object is not iterable (cannot read property Symbol(Symbol.iterator))
    at Function.fromEntries (<anonymous>)
    at <anonymous>:1:8

Seems like an object is getting passed to the function Object.fromEntries() which is also unexpected, I'll create a ticket in the backlog to investigate
