I ran into an The index is outside the matrix limits. error while adding a bundle to my bundleConfig while following this tutorial about the fullCalendar jQuery plugin

these are the bundles. The files are a little bit different than the ones in the tutorial because of newer versions. note: I also tried the older versions after getting the errors

        //Calendar css

        bundles.Add(new StyleBundle(~/Content/fullcalendarcss).Include(

            ~/Content/themes/base/jquery.ui.all.css,

            ~/Content/fullcalendar.css));



        //Calendar script

        bundles.Add(new StyleBundle(~/bundles/fullcalendarjs).Include(

            ~/Scripts/jquery-ui-1.8.11.min.js,

            ~/Scripts/moment.min.js,

            ~/Scripts/fullcalendar.min.js));

while googling for a fix for the error, I came upon this stackoverflow page where the fix was to update the packages. so I did and got the following errors:

Cannot find *projectname* name 'Record' & Cannot find *projectname* name 'undefined' which are both inside the index.d.ts file.

while googling for a fix for those errors, I came upon several pages like this one and this one to name a few, but to no avail.

I'm so confused and I can't find a solution to the Cannot find *projectname* name 'Record' & Cannot find *projectname* name 'undefined' errors.

also I tried to simply take out the line which was giving the error: [name: string]: (BaseModifier & Record<string, any>) | undefined; but that just gave me an System.OutOfMemoryException.

Does anybody know what I should do to resolve this problem?

Thank you kindly.
