Summary

0045657: WebPOS fails with Chrome v89, because of new .at() function in Strings

Description

In Chrome v89, the String prototype has a new at() function. This is a problem with the current implementation of the WebPOS, because the .at function is used to distinguish between Backbone collections and other types of objects.

Steps To Reproduce

Using Chrome Dev branch, log in the WebPOS. Realise the following Javascript error is raised:

Uncaught (in promise) TypeError: clonedObject.get(...).reset is not a function
    at 54efdf8ddc7966329ee58389bd8dd37b.js:14770
    at Array.forEach (<anonymous>)
    at Function.b.each.b.forEach (underscore-1.3.3.min.js:11)
    at cloneRecursively (54efdf8ddc7966329ee58389bd8dd37b.js:14762)
    at Object.OB.UTIL.clone (54efdf8ddc7966329ee58389bd8dd37b.js:14849)
    at G.d.clearWith (54efdf8ddc7966329ee58389bd8dd37b.js:66024)
    at Object.OB.UTIL.TicketUtils.loadAndSyncTicketFromState (54efdf8ddc7966329ee58389b

Proposed Solution

Instead of checking the .at() function, it should be checked whether the object is instance of Backbone.Collection.
