Javascritp error in performing column filter

[Chiara De Acetis]

Hello,

I've created a grid with excel type filtering and server side filter operations.
I've recently upgraded the javascript to the version [15.4.0.17], using https://csg.syncfusion.com/

I've noticed the following error:
Uncaught TypeError: Cannot read property 'toLowerCase' of undefined
    at t.excelFilter._setCheckState
    at t.excelFilter.replacer
    at t.excelFilter._setCheckBoxList
[...omiss...]

I've attached the screenshot of  the error.

Step to reproduce:

1. Create a grid with excel type filtering, UlrAdaptor to get the data.
2. Populate the grid with some data, with a column, say column A, with some null values.
3. Click on the filter icon of column A, uncheck blanks.
4. Click the filter icon of column A again after the grid performed the filtering, the error shows in console.

To work around  this, we edited the downloaded file, adding to the following funciton:
_setCheckState: function (value) { ... }

the following lines (after this one :" val = this.processValue(splts[splen]); " ):
 if (!val) {
     val = '';
}
