reportFilters options die when in an Ember environment

Luke Deniston asked on February 13, 2019

When using the elasticsearch dataSourceType, providing any reportFilters to the slice will result in it dying with “I2y.toLocaleLowerCase is not a function”. I have not tested so I’m not sure this is unique to that dataSourceType.
This is because there’s a for…in loop without a doing a hasOwnProperty check. Ember adds a _super to the Array prototype which is what’s causing the bug. Removing this from the passed in options doesn’t work because it looks like at some point inside Flexmonster the array is cloned.
I’m not sure if this is helpful, but this is the bad code in my minified/obfuscated copy of Flexmonster:

for (var T3y in this.Fn) (P3y = this.cb(this.Fn[T3y])),

It still dies for me inside this function:

                    C79.prototype.Qu = function() {
var c19;
if (j4AA.t7k < this.Fn.length) {
for (var z19 in this.Fn)
c19 = this.cb(this.Fn[z19]),
j4AA.j1k != c19 && (this.GC ?, c19) :, c19));
this.Fn = [];

Here’s the error:

VM69:formatted:21757 Uncaught TypeError: K09.toLocaleLowerCase is not a function

Inserting this code beforehand makes everything work:

delete Array.prototype._super;

But I don’t want to do that since it will break some of our other libraries.
